62a1a58039 HID: hid-sensor-custom: Use scnprintf() for avoiding potential buffer overflow
Since snprintf() returns the would-be-output size instead of the
actual output size, the succeeding calls may go beyond the given
buffer limit.  Fix it by replacing with scnprintf().

8c9d734cdf HID: logitech-dj: add support for the static device in the Powerplay mat/receiver
The Logitech G Powerplay has a lightspeed receiver with a static HID++
device with ID 7 attached to it to. It is used to configure the led on
the mat. For this reason I increased the max number of devices.

789a2c2503 HID: hid-bigbenff: fix general protection fault caused by double kfree
The struct *bigben was allocated via devm_kzalloc() and then used as a
parameter in input_ff_create_memless(). This caused a double kfree
during removal of the device, since both the managed resource API and
ml_ff_destroy() in drivers/input/ff-memless.c would call kfree() on it.

8d2e77b39b HID: alps: Fix an error handling path in 'alps_input_configured()'
They are issues:
   - if 'input_allocate_device()' fails and return NULL, there is no need
     to free anything and 'input_free_device()' call is a no-op. It can
     be axed.
   - 'ret' is known to be 0 at this point, so we must set it to a
     meaningful value before returning

5c02c447ea HID: hiddev: Fix race in in hiddev_disconnect()
Syzbot reports that "hiddev" is used after it's free in hiddev_disconnect().
The hiddev_disconnect() function sets "hiddev->exist = 0;" so
hiddev_release() can free it as soon as we drop the "existancelock"
lock.  This patch moves the mutex_unlock(&hiddev->existancelock) until
after we have finished using it.

The ITE 8595 chip used in various 2-in-1 keyboard docks works fine with
the hid-generic driver (minus the RF_KILL key) and also keeps working fine
when swapping drivers, so there is no need to have it in the
hid_have_special_driver list.

Note the other 2 USB ids in hid-ite.c were never added to

5ebdffd250 HID: core: fix off-by-one memset in hid_report_raw_event()
In case a report is greater than HID_MAX_BUFFER_SIZE, it is truncated,
but the report-number byte is not correctly handled. This results in a
off-by-one in the following memset, causing a kernel Oops and ensuing
system crash.

Note: With commit 8ec321e96e ("HID: Fix slab-out-of-bounds read in
hid_field_extract") I no longer hit the kernel Oops as we instead fail
"controlled" at probe if there is a report too long in the HID
report-descriptor. hid_report_raw_event() is an exported symbol, so
presumabely we cannot always rely on this being the case.

beae56192a HID: ite: Only bind to keyboard USB interface on Acer SW5-012 keyboard dock
Commit 8f18eca9eb ("HID: ite: Add USB id match for Acer SW5-012 keyboard
dock") added the USB id for the Acer SW5-012's keyboard dock to the
hid-ite driver to fix the rfkill driver not working.

Most keyboard docks with an ITE 8595 keyboard/touchpad controller have the
"Wireless Radio Control" bits which need the special hid-ite driver on the
second USB interface (the mouse interface) and their touchpad only supports
mouse emulation, so using generic hid-input handling for anything but
the "Wireless Radio Control" bits is fine. On these devices we simply bind
to all USB interfaces.

But unlike other ITE8595 using keyboard docks, the Acer Aspire Switch 10
(SW5-012)'s touchpad not only does mouse emulation it also supports
HID-multitouch and all the keys including the "Wireless Radio Control"
bits have been moved to the first USB interface (the keyboard intf).

So we need hid-ite to handle the first (keyboard) USB interface and have
it NOT bind to the second (mouse) USB interface so that that can be
handled by hid-multitouch.c and we get proper multi-touch support.

This commit changes the hid_device_id for the SW5-012 keyboard dock to
only match on hid devices from the HID_GROUP_GENERIC group, this way
hid-ite will not bind the the mouse/multi-touch interface which has
HID_GROUP_MULTITOUCH_WIN_8 as group.
This fixes the regression to mouse-emulation mode introduced by adding
the keyboard dock USB id.

Previously we were ignoring extPower, which resulted in wrong values.

Example:
    With an unplugged mouse

    $ cat /sys/class/power_supply/hidpp_battery_0/status
    Charging

This patch fixes that, it also renames charge_sts to flags as
charge_sts can be confused with chargeStatus from the spec.

The `connected` value for wired devices was not properly initialized,
it must be set to `true` upon creation, because wired devices do not
generate connection events.

When a raw client (the Steam Client) uses the device, the input device
is destroyed. Then, when the raw client finishes, it must be recreated.
But since the `connected` variable was false this never happended.

be281368f2 hid-logitech-hidpp: read battery voltage from newer devices
Newer Logitech mice report their battery voltage through feature 0x1001
instead of the battery levels through feature 0x1000.

When the device is brought up and we try to query the battery, figure
out if it supports the old or the new feature. If it supports the new
feature, record the feature index and read the battery voltage and
its charge status. The device will respond with three bytes: the first
two are its voltage, and the last one is a bitset, reporting if the
battery is charging, fast or slow, in critical level or discharging.

If everything went correctly, record the fact that we're capable
of querying battery voltage.

Note that the protocol only gives us the current voltage in mV.
We store that as-is, but when queried, we report it in uV as
expected by sysfs.

Like we do for other ways of interacting with the battery for other
devices, refresh the battery status and notify the power supply
subsystem of the changes in voltage and status.

Since there are no known devices which implement both the old and the
new battery feature, we make sure to try the newer feature first and
only fall back to the old one if that fails.

18a1b06e5b HID: hiddev: fix mess in hiddev_open()
The open method of hiddev handler fails to bring the device out of
autosuspend state as was promised in 0361a28d3f, as it actually has 2
blocks that try to start the transport (call hid_hw_open()) with both
being guarded by the "open" counter, so the 2nd block is never executed as
the first block increments the counter so it is never at 0 when we check
it for the second block.

Additionally hiddev_open() was leaving counter incremented on errors,
causing the device to never be reopened properly if there was ever an
error.

Let's fix all of this by factoring out code that creates client structure
and powers up the device into a separate function that is being called
from usbhid_open() with the "existancelock" being held.

At least on a T100HA an Asus vendor-page usage-code 0xff event is send on
every suspend and again on resume, resulting in the following warning:

asus 0003:0B05:1807.0002: Unmapped Asus vendor usagepage code 0xff

being logged twice on every suspend/resume.

This commit silences the "Unmapped Asus vendor usagepage code ..."
warning for usage-code 0xff to avoid these warnings being logged.

8f18eca9eb HID: ite: Add USB id match for Acer SW5-012 keyboard dock
The Acer SW5-012 2-in-1 keyboard dock uses a Synaptics S91028 touchpad
which is connected to an ITE 8595 USB keyboard controller chip.

This keyboard has the same quirk for its rfkill / airplane mode hotkey as
other keyboards with the ITE 8595 chip, it only sends a single release
event when pressed and released, it never sends a press event.

This commit adds this keyboards USB id to the hid-ite id-table, fixing
the rfkill key not working on this keyboard.

8ec321e96e HID: Fix slab-out-of-bounds read in hid_field_extract
The syzbot fuzzer found a slab-out-of-bounds bug in the HID report
handler.  The bug was caused by a report descriptor which included a
field with size 12 bits and count 4899, for a total size of 7349
bytes.

The usbhid driver uses at most a single-page 4-KB buffer for reports.
In the test there wasn't any problem about overflowing the buffer,
since only one byte was received from the device.  Rather, the bug
occurred when the HID core tried to extract the data from the report
fields, which caused it to try reading data beyond the end of the
allocated buffer.

This patch fixes the problem by rejecting any report whose total
length exceeds the HID_MAX_BUFFER_SIZE limit (minus one byte to allow
for a possible report index).  In theory a device could have a report
longer than that, but if there was such a thing we wouldn't handle it
correctly anyway.

9f3b61dc1d HID: hidraw: Fix returning EPOLLOUT from hidraw_poll
When polling a connected /dev/hidrawX device, it is useful to get the
EPOLLOUT when writing is possible. Since writing is possible as soon as
the device is connected, always return it.

Right now EPOLLOUT is only returned when there are also input reports
are available. This works if devices start sending reports when
connected, but some HID devices might need an output report first before
sending any input reports. This change will allow using EPOLLOUT here as
well.

 This series incorporates some of Al's work and many patches of my own,

 more testing or possibly a rewrite.

During the suspend process and resume process, if there is any mouse

This behavior can be avoided by disabling the Hyper-V mouse device as
a wakeup source:

In the event that the RMI device is unreachable, the calls to rmi_set_mode() or
rmi_set_page() will fail before registering the RMI transport device. When the
device is removed, rmi_remove() will call rmi_unregister_transport_device()
which will attempt to access the rmi_dev pointer which was not set.
This patch adds a check of the RMI_STARTED bit before calling
rmi_unregister_transport_device().  The RMI_STARTED bit is only set
after rmi_register_transport_device() completes successfully.

2dbc6f113a HID: Improve Windows Precision Touchpad detection.
Per Microsoft spec, usage 0xC5 (page 0xFF) returns a blob containing
data used to verify the touchpad as a Windows Precision Touchpad.

   0x85, REPORTID_PTPHQA,    //    REPORT_ID (PTPHQA)
    0x09, 0xC5,              //    USAGE (Vendor Usage 0xC5)
    0x15, 0x00,              //    LOGICAL_MINIMUM (0)
    0x26, 0xff, 0x00,        //    LOGICAL_MAXIMUM (0xff)

    0xb1, 0x02,              //    FEATURE (Data,Var,Abs)

However, some devices, namely Microsoft's Surface line of products
instead implement a "segmented device certification report" (usage 0xC6)
which returns the same report, but in smaller chunks.

    0x06, 0x00, 0xff,        //     USAGE_PAGE (Vendor Defined)
    0x85, REPORTID_PTPHQA,   //     REPORT_ID (PTPHQA)
    0x09, 0xC6,              //     USAGE (Vendor usage for segment #)
    0x25, 0x08,              //     LOGICAL_MAXIMUM (8)
    0x75, 0x08,              //     REPORT_SIZE (8)
    0x95, 0x01,              //     REPORT_COUNT (1)
    0xb1, 0x02,              //     FEATURE (Data,Var,Abs)
    0x09, 0xC7,              //     USAGE (Vendor Usage)
    0x26, 0xff, 0x00,        //     LOGICAL_MAXIMUM (0xff)
    0x95, 0x20,              //     REPORT_COUNT (32)
    0xb1, 0x02,              //     FEATURE (Data,Var,Abs)

By expanding Win8 touchpad detection to also look for the segmented
report, all Surface touchpads are now properly recognized by
hid-multitouch.

1cb0d2aee2 HID: core: check whether Usage Page item is after Usage ID items
Upstream commit 58e7515500 ("HID: core: move Usage Page concatenation
to Main item") adds support for Usage Page item after Usage ID items
(such as keyboards manufactured by Primax).

Usage Page concatenation in Main item works well for following report
descriptor patterns:

    USAGE_PAGE (Keyboard)                   05 07
    USAGE_MINIMUM (Keyboard LeftControl)    19 E0
    USAGE_MAXIMUM (Keyboard Right GUI)      29 E7
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (8)                        95 08
    INPUT (Data,Var,Abs)                    81 02

-------------

    USAGE_MINIMUM (Keyboard LeftControl)    19 E0
    USAGE_MAXIMUM (Keyboard Right GUI)      29 E7
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (8)                        95 08
    USAGE_PAGE (Keyboard)                   05 07
    INPUT (Data,Var,Abs)                    81 02

But it makes the parser act wrong for the following report
descriptor pattern(such as some Gamepads):

    USAGE_PAGE (Button)                     05 09
    USAGE (Button 1)                        09 01
    USAGE (Button 2)                        09 02
    USAGE (Button 4)                        09 04
    USAGE (Button 5)                        09 05
    USAGE (Button 7)                        09 07
    USAGE (Button 8)                        09 08
    USAGE (Button 14)                       09 0E
    USAGE (Button 15)                       09 0F
    USAGE (Button 13)                       09 0D
    USAGE_PAGE (Consumer Devices)           05 0C
    USAGE (Back)                            0a 24 02
    USAGE (HomePage)                        0a 23 02
    LOGICAL_MINIMUM (0)                     15 00
    LOGICAL_MAXIMUM (1)                     25 01
    REPORT_SIZE (1)                         75 01
    REPORT_COUNT (11)                       95 0B
    INPUT (Data,Var,Abs)                    81 02

With Usage Page concatenation in Main item, parser recognizes all the
11 Usages as consumer keys, it is not the HID device's real intention.

This patch checks whether Usage Page is really defined after Usage ID
items by comparing usage page using status.

Usage Page concatenation on currently defined Usage Page will always
do in local parsing when Usage ID items encountered.

When Main item is parsing, concatenation will do again with last
defined Usage Page if this page has not been used in the previous
usages concatenation.

ff479731c3 HID: wacom: generic: Treat serial number and related fields as unsigned
The HID descriptors for most Wacom devices oddly declare the serial
number and other related fields as signed integers. When these numbers
are ingested by the HID subsystem, they are automatically sign-extended
into 32-bit integers. We treat the fields as unsigned elsewhere in the
kernel and userspace, however, so this sign-extension causes problems.
In particular, the sign-extended tool ID sent to userspace as ABS_MISC
does not properly match unsigned IDs used by xf86-input-wacom and libwacom.

We introduce a function 'wacom_s32tou' that can undo the automatic sign
extension performed by 'hid_snto32'. We call this function when processing
the serial number and related fields to ensure that we are dealing with
and reporting the unsigned form. We opt to use this method rather than
adding a descriptor fixup in 'wacom_hid_usage_quirk' since it should be
more robust in the face of future devices.

43b7029f47 HID: i2c-hid: Send power-on command after reset
Before commit 67b18dfb8c ("HID: i2c-hid: Remove runtime power
management"), any i2c-hid touchscreens would typically be runtime-suspended
between the driver loading and Xorg or a Wayland compositor opening it,
causing it to be resumed again. This means that before this change,
we would call i2c_hid_set_power(OFF), i2c_hid_set_power(ON) before the
graphical session would start listening to the touchscreen.

It turns out that at least some SIS touchscreens, such as the one found
on the Asus T100HA, need a power-on command after reset, otherwise they
will not send any events.

1832f2d8ff compat_ioctl: move more drivers to compat_ptr_ioctl
The .ioctl and .compat_ioctl file operations have the same prototype so
they can both point to the same function, which works great almost all
the time when all the commands are compatible.

One exception is the s390 architecture, where a compat pointer is only
31 bit wide, and converting it into a 64-bit pointer requires calling
compat_ptr(). Most drivers here will never run in s390, but since we now
have a generic helper for it, it's easy enough to use it consistently.

I double-checked all these drivers to ensure that all ioctl arguments
are used as pointers or are ignored, but are not interpreted as integer
values.

905d754c53 HID: logitech-hidpp: rework device validation
G920 device only advertises REPORT_ID_HIDPP_LONG and
REPORT_ID_HIDPP_VERY_LONG in its HID report descriptor, so querying
for REPORT_ID_HIDPP_SHORT with optional=false will always fail and
prevent G920 to be recognized as a valid HID++ device.

To fix this and improve some other aspects, modify
hidpp_validate_device() as follows:

  - Inline the code of hidpp_validate_report() to simplify
    distingushing between non-present and invalid report descriptors

  - Drop the check for id >= HID_MAX_IDS || id < 0 since all of our
    IDs are static and known to satisfy that at compile time

  - Change the algorithms to check all possible report
    types (including very long report) and deem the device as a valid
    HID++ device if it supports at least one

  - Treat invalid report length as a hard stop for the validation
    algorithm, meaning that if any of the supported reports has
    invalid length we assume the worst and treat the device as a
    generic HID device.

  - Fold initialization of hidpp->very_long_report_length into
    hidpp_validate_device() since it already fetches very long report
    length and validates its value

abdd3d0b34 HID: logitech-hidpp: split g920_get_config()
Original version of g920_get_config() contained two kind of actions:

    1. Device specific communication to query/set some parameters
       which requires active communication channel with the device,
       or, put in other way, for the call to be sandwiched between
       hid_device_io_start() and hid_device_io_stop().

    2. Input subsystem specific FF controller initialization which, in
       order to access a valid 'struct hid_input' via
       'hid->inputs.next', requires claimed hidinput which means be
       executed after the call to hid_hw_start() with connect_mask
       containing HID_CONNECT_HIDINPUT.

Location of g920_get_config() can only fulfill requirements for #1 and
not #2, which might result in following backtrace:

To solve this issue:

   1. Split g920_get_config() such that all of the device specific
      communication remains a part of the function and input subsystem
      initialization bits go to hidpp_ff_init()

   2. Move call to hidpp_ff_init() from being a part of
      g920_get_config() to be the last step of .probe(), right after a
      call to hid_hw_start() with connect_mask containing
      HID_CONNECT_HIDINPUT.

67b18dfb8c HID: i2c-hid: Remove runtime power management
Runtime power management in i2c-hid brings lots of issues, such as:
- When transitioning from display manager to desktop session, i2c-hid
was closed and opened, so the device was set to SLEEP and ON in a short
period. Vendors confirmed that their devices can't handle fast ON/SLEEP
command because Windows doesn't have this behavior.

- When rebooting, i2c-hid was closed, and the driver core put the device
back to full power before shutdown. This behavior also triggers a quick
SLEEP and ON commands that some devices can't handle, renders an
unusable touchpad after reboot.

- Most importantly, my power meter reports little to none energy saving
when i2c-hid is runtime suspended.

So let's remove runtime power management since there is no actual
benefit.

d9d4b1e46d HID: Fix assumption that devices have inputs
The syzbot fuzzer found a slab-out-of-bounds write bug in the hid-gaff
driver.  The problem is caused by the driver's assumption that the
device must have an input report.  While this will be true for all
normal HID input devices, a suitably malicious device can violate the
assumption.

The same assumption is present in over a dozen other HID drivers.
This patch fixes them by checking that the list of hid_inputs for the
hid_device is nonempty before allowing it to be used.

ad4203f5a2 HID: lg-g15: Add support for the G510 keyboards' gaming keys
Add support for the gaming and LCD menu keys on the G510 keyboard.

Note this commit does not add support for the keyboard and LCD backlight
and the status LEDs, this is done in a follow up commit.

Note the G510 generates 4 different input reports on its second
(Consumer Keys) interface:

-input report 1 is standard bootclass keyboard input report, mirroring
 normal keyboard interface
-input report 2 is consumer page keys
-input report 3 is gkeys, etc.
-input report 4 is LED status, single byte, bits:
 bit 2: kbd and LCD backlight is *off* when set, toggled by the light key
 bit 3: headphone mute LED
 bit 4: mic mute LED

Input-report 1 we ignore since this is a duplicate report from the first
interface, report 2 is handled by the regular hid-input code. In this
commit we add handling for input report 3.

79085c7dd2 HID: google: whiskers: signal tablet mode switch on disconnect
Currently, the tablet mode switch that takes two signals as its input:
base attached switch from the EC and some GMR signal from whiskers when
it's folded over. This tablet mode switch is then sent to Chrome, which
changes the UI.

However, there are some units which have a lot of leakage on the ADC
pins that the EC uses to determine whether or not a base is attached.
This can result in the base being physically detached, but the EC
thinking that it's still attached. The user would then be stuck in
laptop mode and wouldn't be able to rotate their display.

To work around this let's send "tablet mode" signal when we remove HID
interface, which normally happens when we physically disconnect
whiskers.

The USB interface may get detected before the platform/EC one, so let's
note the state of the base (if we receive event) and use it to correctly
initialize the tablet mode switch state.

Also let's start the HID interface immediately when probing, this will
ensure that we correctly process "base folded" events that may be sent
as we initialize the base. Note that this requires us to add a remove()
function where we stop and close the hardware and switch the LED
registration away from devm interface as we need to make sure that we
destroy the LED instance before we stop the hardware.

0af10eed9b HID: core: fix dmesg flooding if report field larger than 32bit
Only warn once of oversize hid report value field

On HP spectre x360 convertible the message:
hid-sensor-hub 001F:8087:0AC2.0002: hid_field_extract() called with n (192) > 32! (kworker/1:2)
is continually printed many times per second, crowding out all else.
Protect dmesg by printing the warning only one time.

The size of the hid report field data structure should probably be increased.
The data structure is treated as a u32 in Linux, but an unlimited number
of bits in the USB hid spec, so there is some rearchitecture needed now that
devices are sending more than 32 bits.

8bb3537095 Bluetooth: hidp: Fix assumptions on the return value of hidp_send_message
hidp_send_message was changed to return non-zero values on success,
which some other bits did not expect. This caused spurious errors to be
propagated through the stack, breaking some drivers, such as hid-sony
for the Dualshock 4 in Bluetooth mode.

As pointed out by Dan Carpenter, hid-microsoft directly relied on that
assumption as well.

The problem is caused by the fact that pcmidi_get_output_report() will
return an error if the HID device doesn't provide the right sort of

the return code and assumes the function call always succeeds.

This patch adds the missing check and aborts the probe operation if
necessary.

aec256d0ec HID: apple: Fix stuck function keys when using FN
This fixes an issue in which key down events for function keys would be
repeatedly emitted even after the user has raised the physical key. For
example, the driver fails to emit the F5 key up event when going through
the following steps:
- fnmode=1: hold FN, hold F5, release FN, release F5
- fnmode=2: hold F5, hold FN, release F5, release FN

The repeated F5 key down events can be easily verified using xev.

840d9f131f mfd / platform: cros_ec: Reorganize platform and mfd includes
There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.

In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:

 - Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
 - Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
   driver from include/linux/mfd/cros_ec.h to a new file
   include/linux/platform_data/cros_ec_proto.h
 - Update all the drivers with the new includes, so
   - Drivers that only need to know about the protocol include
     - linux/platform_data/cros_ec_proto.h
     - linux/platform_data/cros_ec_commands.h
   - Drivers that need to know about the cros-ec mfd device also include
     - linux/mfd/cros_ec.h

8ccff2843f HID: logitech-dj: Fix crash when initial logi_dj_recv_query_paired_devices fails
Before this commit dj_probe would exit with an error if the initial
logi_dj_recv_query_paired_devices fails. The initial call may fail
when the receiver is connected through a kvm and the focus is away.

When the call fails this causes 2 problems:

1) dj_probe calls logi_dj_recv_query_paired_devices after calling
hid_device_io_start() so a HID report may have been received in between
and our delayedwork_callback may be running. It seems that the initial
logi_dj_recv_query_paired_devices failure happening with some KVMs triggers
this exact scenario, causing the work-queue to run on free-ed memory,
leading to:

2) Even if we were to fix 1. by making sure the work is stopped before
failing probe, failing probe is the wrong thing to do, we have
logi_dj_recv_queue_unknown_work to deal with the initial
logi_dj_recv_query_paired_devices failure.

Rather then error-ing out of the probe, causing the receiver to not work at
all we should rely on this, so that the attached devices will get properly
enumerated once the KVM focus is switched back.

69ecd44d68 HID: multitouch: add support for the Smart Tech panel
This panel is not very friendly to us:
it exposes multiple multitouch collections, some of them being of
logical application stylus.

Usually, a device has only one report per application, and that is
what I assumed in commit 8dfe14b3b4 ("HID: multitouch: ditch mt_report_id")

To avoid breaking all working device, add a new class and a new quirk
for that situation.

c23e2043d5 HID: multitouch: do not filter mice nodes
It was a good idea at the time to not create a mouse node for the
multitouch touchscreens, but:
- touchscreens following the Win 8 protocol should not have this
  disturbing mouse node anymore, or if they have, it should be
  used for something else (like a joystick attached to the screen)
- touchpads have it, and they should not use it unless there is a bug,
  but when the laptop has a trackstick, the data are reported through this
  mouse node.

So instead of whitelisting all of the devices that have a need for the
mouse node, just export it.
hid-input.c will append a suffix to it ('Mouse'), so users will eventually
see if something goes wrong.

87fcb6a69e HID: do not call hid_set_drvdata(hdev, NULL) in drivers
This is a common pattern in the HID drivers to reset the drvdata. Some
do it properly, some do it only in case of failure.

But, this is actually already handled by driver core, so there is no need

670e90924b HID: wacom: support named keys on older devices
Some Wacom devices have keys with predefined meanings. However, when
support was originally added for these devices, the codes for these
keys were not available yet. These keys were thus reported with
the numbered KEY_PROG* range.

Some missing key codes were added with commit 4eb220cb35 ("HID:
wacom: generic: add 3 tablet touch keys") and we are now able to
report the proper key codes. We continue to report the original
KEY_PROG codes so as not to break any unknown applications that
may depend on them.

Also, to support the touch key, track its state in the pad report.

c1ca58f698 HID: intel-ish-hid: ipc: set NO_D3 flag only when needed
Currently, the NO_D3 flag is set in ish_probe(), and cleared in
ish_remove(). So even if the system goes into S3, ISH is still
in D0i3 state. It makes more sense that put ISH into D3 as system
goes into S3 and put ISH into D0i3 as system goes into suspend-to-idle.
I remove the NO_D3 setting in ish_probe(), so that ISH can enter
D3 state when system enters S3. Only set N0_D3 flag when system
enters the suspend-to-idle or platform specified, and clear it
when system resume.

When the ISH enters D3, the FW will check the DMA bit status.
If the DMA bit is set, the FW will reset automatically. So the
DMA bit need be clear before putting ISH into D3 state.

e0f6974a54 HID: sony: Fix race condition between rumble and device remove.
Valve reported a kernel crash on Ubuntu 18.04 when disconnecting a DS4
gamepad while rumble is enabled. This issue is reproducible with a
frequency of 1 in 3 times in the game Borderlands 2 when using an
automatic weapon, which triggers many rumble operations.

We found the issue to be a race condition between sony_remove and the
final device destruction by the HID / input system. The problem was
that sony_remove didn't clean some of its work_item state in
"struct sony_sc". After sony_remove work, the corresponding evdev
node was around for sufficient time for applications to still queue
rumble work after "sony_remove".

On pre-4.19 kernels the race condition caused a kernel crash due to a
NULL-pointer dereference as "sc->output_report_dmabuf" got freed during
sony_remove. On newer kernels this crash doesn't happen due the buffer
now being allocated using devm_kzalloc. However we can still queue work,
while the driver is an undefined state.

This patch fixes the described problem, by guarding the work_item
"state_worker" with an initialized variable, which we are setting back
to 0 on cleanup.

1c703b53e5 HID: input: fix a4tech horizontal wheel custom usage
Some a4tech mice use the 'GenericDesktop.00b8' usage to inform whether
the previous wheel report was horizontal or vertical. Before
c01908a14b ("HID: input: add mapping for "Toggle Display" key") this
usage was being mapped to 'Relative.Misc'. After the patch it's simply
ignored (usage->type == 0 & usage->code == 0). Which ultimately makes
hid-a4tech ignore the WHEEL/HWHEEL selection event, as it has no
usage->type.

We shouldn't rely on a mapping for that usage as it's nonstandard and
doesn't really map to an input event. So we bypass the mapping and make
sure the custom event handling properly handles both reports.

7bc74853fd HID: quirks: Set the INCREMENT_USAGE_ON_DUPLICATE quirk on Saitek X52
The Saitek X52 joystick has a pair of axes that are originally
(by the Windows driver) used as mouse pointer controls. The corresponding
usage->hid values are 0x50024 and 0x50026. Thus they are handled
as unknown axes and both get mapped to ABS_MISC. The quirk makes
the second axis to be mapped to ABS_MISC1 and thus made available
separately.

378b80370a hidraw: Return EPOLLOUT from hidraw_poll
Always return EPOLLOUT from hidraw_poll when a device is connected.
This is safe since writes are always possible (but will always block).

hidraw does not support non-blocking writes and instead always calls
blocking backend functions on write requests. Hence, so far, a call to
poll never returned EPOLLOUT, which confuses tools like socat.

6fb08f1a5f HID: logitech-dj: Really fix return value of logi_dj_recv_query_hidpp_devices
Commit dbcbabf7da ("HID: logitech-dj: fix return value of
logi_dj_recv_query_hidpp_devices") made logi_dj_recv_query_hidpp_devices
return the return value of hid_hw_raw_request instead of unconditionally
returning 0.

But hid_hw_raw_request returns the report-size on a successful request
(and a negative error-code on failure) where as the callers of
logi_dj_recv_query_hidpp_devices expect a 0 return on success.

This commit fixes things so that either the negative error gets returned
or 0 on success, fixing HID++ receivers such as the Logitech nano receivers
no longer working.

fcd98147ac stream_open related bits for Linux 5.3
- the first one converts stream_open.cocci to treat all functions that
   start with wait_.* as blocking. Previously it was only wait_event_.*
   functions that were considered as blocking, but this was falsely
   reporting several deadlock cases as only warning. The patch was
   picked by linux-kbuild and entered mainline as 0c4ab18fc3.
   It is thus omitted from hereby pull-request.
 
 - the second one teaches stream_open.cocci to consider files as being

Merge tag 'stream_open-5.3' of https://lab.nexedi.com/kirr/linux

Pull stream_open() updates from Kirill Smelkov:
 "This time on stream_open front it is only two small changes:

   - the first one converts stream_open.cocci to treat all functions
     that start with wait_.* as blocking. Previously it was only
     wait_event_.* functions that were considered as blocking, but this
     was falsely reporting several deadlock cases as only warning.

     This was picked by linux-kbuild and entered mainline as commit
     0c4ab18fc3 ("coccinelle: api/stream_open: treat all wait_.*()
     calls as blocking"), and already merged earlier.

   - the second one teaches stream_open.cocci to consider files as being
     stream-like even if they use noop_llseek. It results in two more
     drivers being converted to stream_open() (mousedev.c and
     hid-sensor-custom.c)"

5516745311 platform-drivers-x86 for v5.3-1
ASUS WMI driver got a big refactoring in order to support the TUF Gaming
 laptops. Besides that, the regression with backlight being permanently off
 on various EeePC laptops has been fixed.
 
 Accelerometer on HP ProBook 450 G0 shows wrong measurements due to
 X axis being inverted. This has been fixed.
 
 Intel PMC core driver has been extended to be ACPI enumerated
 if the DSDT provides device with _HID "INT33A1". This allows
 to convert the driver to be pure platform and support new hardware
 purely based on ACPI DSDT.
 
 From now on the Intel Speed Select Technology is supported thru
 a corresponding driver. This driver provides an access to the features
 of the ISST, such as Performance Profile, Core Power, Base frequency and
 Turbo Frequency.
 
 Mellanox platform drivers has been refactored and now extended
 to support more systems, including new coming ones.
 
 The OLPC XO-1.75 platform is now supported.
 
 CB4063 Beckhoff Automation board is using PMC clocks,
 provided via pmc_atom driver, for ethernet controllers in a way
 that they can't be managed by the clock driver. The quirk
 has been extended to cover this case.
 
 Touchscreen on Chuwi Hi10 Plus tablet has been enabled. Meanwhile
 the information of Chuwi Hi10 Air has been fixed to cover more models
 based on the same platform.
 
 Xiaomi notebooks have WMI interface enabled. Thus, the driver to support it
 has been provided. It required some extension of the generic WMI library,
 which allows to propagate opaque context to the ->probe() of the
 individual drivers.
 
 This release includes debugfs clean up from Greg KH for several drivers
 that drop return code check and make debugfs absence or failure non-fatal.
 
 Miscellaneous fixes here and there, mostly for Acer WMI and
 various Intel drivers.

3975b097e5 *: convert stream-like files -> stream_open, even if they use noop_llseek
This patch continues 10dce8af34 (fs: stream_open - opener for
stream-like files so that read and write can run simultaneously without
deadlock) and c5bf68fe0c (*: convert stream-like files from
nonseekable_open -> stream_open) and teaches steam_open.cocci to
consider files as being stream-like not only if they have
.llseek=no_llseek, but also if they have .llseek=noop_llseek.

This is safe to do: the comment about noop_llseek says

	This is an implementation of ->llseek useable for the rare special case when
	userspace expects the seek to succeed but the (device) file is actually not
	able to perform the seek. In this case you use noop_llseek() instead of
	falling back to the default implementation of ->llseek.

and in general noop_llseek was massively added to drivers in 6038f373a3
(llseek: automatically add .llseek fop) when changing default for NULL .llseek
from NOP to no_llseek with the idea to avoid breaking compatibility, if
maybe some user-space program was using lseek on a device without caring
about the result, but caring if it was an error or not.

Amended semantic patch produces two changes when applied tree-wide:

        drivers/hid/hid-sensor-custom.c:690:8-24: WARNING: hid_sensor_custom_fops: .read() has stream semantic; safe to change nonseekable_open -> stream_open.
        drivers/input/mousedev.c:564:1-17: ERROR: mousedev_fops: .read() can deadlock .write(); change nonseekable_open -> stream_open to fix.

Merge tag 'gpio-v5.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

Pull GPIO updates from Linus Walleij:
 "This is the big slew of GPIO changes for the v5.3 kernel cycle. This
  is mostly incremental work this time.

  Three important things:

   - The FMC subsystem is deleted through my tree. This happens through
     GPIO as its demise was discussed in relation to a patch decoupling
     its GPIO implementation from the standard way of handling GPIO. As
     it turns out, that is not the only subsystem it reimplements and
     the authors think it is better do scratch it and start over using
     the proper kernel subsystems than try to polish the rust shiny. See
     the commit (ACKed by the maintainers) for details.

   - Arnd made a small devres patch that was ACKed by Greg and goes into
     the device core.

   - SPDX header change colissions may happen, because at times I've
     seen that quite a lot changed during the -rc:s in regards to SPDX.
     (It is good stuff, tglx has me convinced, and it is worth the
     occasional pain.)

  Apart from this is is nothing controversial or problematic.

  Summary:

  Core:

   - When a gpio_chip request GPIOs from itself, it can now fully
     control the line characteristics, both machine and consumer flags.
     This makes a lot of sense, but took some time before I figured out
     that this is how it has to work.

   - Several smallish documentation fixes.

d69f62bed7 HID: quirks: Refactor ELAN 400 and 401 handling
There needs to be coordination between hid-quirks and the elan_i2c driver
about which devices are handled by what drivers.  Currently, both use
whitelists, which results in valid devices being unhandled by default,
when they should not be rejected by hid-quirks.  This is quickly becoming
an issue.

Since elan_i2c has a maintained whitelist of what devices it will handle,
which is now in a header file that hid-quirks can access, use that to
implement a blacklist in hid-quirks so that only the devices that need to
be handled by elan_i2c get rejected by hid-quirks, and everything else is
handled by default.

we can omit printing extra error message in drivers (which BTW is
what the majority of framebuffer_alloc() users is doing already).

b12bbdc5dd HID: intel-ish-hid: fix wrong driver_data usage
Currently, in suspend() and resume(), ishtp client drivers are using
driver_data to get "struct ishtp_cl_device" object which is set by
bus driver. It's wrong since the driver_data should not be owned bus.
driver_data should be owned by the corresponding ishtp client driver.
Due to this, some ishtp client driver like cros_ec_ishtp which uses
its driver_data to transfer its data to its child doesn't work correctly.

So this patch removes setting driver_data in bus drier and instead of
using driver_data to get "struct ishtp_cl_device", since "struct device"
is embedded in "struct ishtp_cl_device", we introduce a helper function
that returns "struct ishtp_cl_device" from "struct device".

The HID++ spec also defines very long HID++ reports, with a reportid of

Userspace (libmx5000) supports this, in order for this to work when talking

we need to properly forward these reports to the device.

e0668f2888 platform/x86: asus-wmi: Improve DSTS WMI method ID detection
The DSTS method detection mistakenly selects DCTS instead of DSTS if
nothing is returned when the method ID is not defined in WMNB. As a result,
the control of keyboard backlight is not functional for TUF Gaming series
laptops. Implement detection based on _UID of the WMI device instead.

There is evidence that DCTS is handled by ACPI WMI devices that have _UID
ASUSWMI, whereas none of the devices without ASUSWMI respond to DCTS and
DSTS is used instead [1].

DSDT examples:

FX505GM (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (Zero)
    }
    ...
    // No return
}

K54C (_UID ATK):
Method (WMNB, 3, Serialized)
{ ...
    If ((Local0 == 0x53545344))
    {
        ...
        Return (0x02)
    }
    ...
    Return (0xFFFFFFFE)
}

That is, the first half of a group of simultaneous touches may

be at the beginning of the next report.

Also some chunks contain no data and potentially some chunks could
contain leftover (bad) data.

device uses to let us know if we should process a chunk of data.

To do this we submit the feature report as a event report

5923ea6c2c gpio: pass lookup and descriptor flags to request_own
When a gpio_chip wants to request a descriptor from itself
using gpiochip_request_own_desc() it needs to be able to specify
fully how to use the descriptor, notably line inversion
semantics. The workaround in the gpiolib.c can be removed
and cases (such as SPI CS) where we need at times to request
a GPIO with line inversion semantics directly on a chip for
workarounds, can be fully supported with this call.

Fix up some users of the API that weren't really using the
last flag to set up the line as input or output properly
but instead just calling direction setting explicitly
after requesting the line.

3ed224e273 HID: logitech-dj: Fix 064d:c52f receiver support
The c52f nano receiver is a mouse only receiver. This means that it needs
some special handling compared to the c534 nano receiver:

1) It sends unnumbered mouse reports with a size of 8 bytes, so we need
   to extend the unnumbered mouse report handling to support reports upto
   8 bytes large

2) It mouse reports have the same high-resolution format as those from the
   gaming mouse receivers

3) It can report consumer/multimedia buttons on its second interface, since
   this is a mouse-only receiver these must be forwarded to the mouse child
   device and not to the keyboard child-device (which will not exist)
