Code which interacts with timestamps needs to use the ktime_t type
returned by functions like ktime_get. The int type does not offer
enough space to store these values, and attempting to use it is a
recipe for problems. In this particular case, overflows would occur
when calculating/storing timestamps leading to incorrect values being
reported to userspace. In some cases these bad timestamps cause input
handling in userspace to appear hung.

The hidraw_open() function increments the hidraw device reference
counter. The counter has no dedicated synchronization mechanism,
resulting in a potential data race when concurrently opening a device.
The race is a regression introduced by commit 8590222e4b ("HID:
hidraw: Replace hidraw device table mutex with a rwsem"). While
minors_rwsem is intended to protect the hidraw_table itself, by instead
acquiring the lock for writing, the reference counter is also protected.
This is symmetrical to hidraw_release().

HP Elite Presenter Mouse HID Record Descriptor shows
two mouses (Repord ID 0x1 and 0x2), one keypad (Report ID 0x5),
two Consumer Controls (Report IDs 0x6 and 0x3).
Previous to this commit it registers one mouse, one keypad
and one Consumer Control, and it was usable only as a
digitl laser pointer (one of the two mouses). This patch defines
the 464a USB device ID and enables the HID_QUIRK_MULTI_INPUT
quirk for it, allowing to use the device both as a mouse
and a digital laser pointer.

In the beginning, commit 18eeef46d3 ("HID: i2c-hid: goodix: Tie the
reset line to true state of the regulator") introduced a change to tie
the reset line of the Goodix touchscreen to the state of the regulator
to fix a power leakage issue in suspend.
After some time, the change was deemed unnecessary and was reverted in
commit 557e05fa9f ("HID: i2c-hid: goodix: Stop tying the reset line to
the regulator") due to difficulties in managing regulator notifiers for
designs like Evoker, which provides a second power rail to touchscreen.
However, the revert caused a power regression on another Chromebook
device Steelix in the field, which has a dedicated always-on regulator
for touchscreen and was covered by the workaround in the first commit.
To address both cases, this patch adds the support for the new
"goodix,no-reset-during-suspend" property in the driver:
- When set to true, the driver does not assert the reset GPIO during
power-down.
Instead, the GPIO will be asserted during power-up to ensure the
touchscreen always has a clean start and consistent behavior after
resuming.
This is for designs with a dedicated always-on regulator.
- When set to false or unset, the driver uses the original control flow
and asserts GPIO and disables regulators normally.
This is for the two-regulator and shared-regulator designs.

Currently, rumble is only supported via bluetooth on a single xbox
controller, called 'model 1708'. On the back of the device, it's named
'wireless controller for xbox one'. However, in 2021, Microsoft released
a firmware update for this controller. As part of this update, the HID
descriptor of the device changed. The product ID was also changed from
0x02fd to 0x0b20. On this controller, rumble was supported via
hid-microsoft, which matched against the old product id (0x02fd). As a
result, the firmware update broke rumble support on this controller.
See:
https://news.xbox.com/en-us/2021/09/08/xbox-controller-firmware-update-rolling-out-to-insiders-starting-today/
The hid-microsoft driver actually supports rumble on the new firmware,
as well. So simply adding new product id is sufficient to bring back
this support.
After discussing further with the xbox team, it was pointed out that
another xbox controller, xbox elite series 2, can be supported in a
similar way.
Add rumble support for all of these devices in this patch. Two of the
devices have received firmware updates that caused their product id's to
change. Both old and new firmware versions of these devices were tested.
The tested controllers are:
1. 'wireless controller for xbox one', model 1708
2. 'xbox wireless controller', model 1914. This is also sometimes
referred to as 'xbox series S|X'.
3. 'elite series 2', model 1797.
The tested configurations are:
1. model 1708, pid 0x02fd (old firmware)
2. model 1708, pid 0x0b20 (new firmware)
3. model 1914, pid 0x0b13
4. model 1797, pid 0x0b05 (old firmware)
5. model 1797, pid 0x0b22 (new firmware)
I verified rumble support on both bluetooth and usb.

If an attempt at contacting a receiver or a device fails because the
receiver or device never responds, don't restart the communication, only
restart it if the receiver or device answers that it's busy, as originally
intended.
This was the behaviour on communication timeout before commit 586e8fede7
("HID: logitech-hidpp: Retry commands when device is busy").
This fixes some overly long waits in a critical path on boot, when
checking whether the device is connected by getting its HID++ version.

More and more drivers rely on devres to manage their resources, however
if bus' probe() and release() methods are not trivial and control some
of resources as well (for example enable or disable clocks, or attach
device to a power domain), we need to make sure that driver-allocated
resources are released immediately after driver's remove() method
returns, and not postponed until driver core gets around to releasing
resources.
In case of HID we should not try to close the report and release
associated memory until after all devres callbacks are executed. To fix
that we open a new devres group before calling driver's probe() and
explicitly release it when we return from driver's remove().
This is similar to what we did for I2C bus in commit 5b5475826c ("i2c:
ensure timely release of driver-allocated resources"). It is tempting to
try and move this into driver core, but actually doing so is challenging,
we need to split bus' remove() method into pre- and post-remove methods,
which would make the logic even less clear.

hid_device_probe() has a complex flow and locks and unlocks a mutex.
Move the most of the logic into __hid_device_probe() and
hid_check_device_match() and leave the locking in hid_device_probe()
which makes the code more clear.

Sensors are enabled independently of HID device initialization. Sensor
initialization should be kept separate in this case, while HID devices
should be initialized according to the sensor state. Hence split sensor
initialization and HID initialization for SFH1.1 into separate blocks.

These two keys are found on some models with dual display.
- 0x6a is intended for controlling the secondary screen brightness.
- 0x4b is intended for toggling the arrow keys between arrows and
page up / page down.
This key is found on a slightly modified keyboard layout.
- 0xc7 is intended to cycle through keybvoard brightnesses (upwards) but
there is not suitable existing code for this behaviour. Using
`KEY_KBDILLUMTOGGLE` is different behaviour to Windows but at least
is picked up by many desktops already.

The strscpy function is able to return an error code when a copy would
overflow the size of the destination. The copy is stopped and the buffer
terminated before overflow actually occurs so it is safe to continue
execution, but we should still produce a warning should this occur.

Use info->screen_buffer when reading and writing framebuffers in
system memory. It's the correct pointer for this address space.
The struct fb_info has a union to store the framebuffer memory. This can
either be info->screen_base if the framebuffer is stored in I/O memory,
or info->screen_buffer if the framebuffer is stored in system memory.
As the driver operates on the latter address space, it is wrong to use
.screen_base and .screen_buffer must be used instead. This also gets
rid of casting needed due to not using the correct data type.

Here is the large set of driver core changes for 6.4-rc1.
Once again, a busy development cycle, with lots of changes happening in
the driver core in the quest to be able to move "struct bus" and "struct
class" into read-only memory, a task now complete with these changes.
This will make the future rust interactions with the driver core more
"provably correct" as well as providing more obvious lifetime rules for
all busses and classes in the kernel.
The changes required for this did touch many individual classes and
busses as many callbacks were changed to take const * parameters
instead. All of these changes have been submitted to the various
subsystem maintainers, giving them plenty of time to review, and most of
them actually did so.
Other than those changes, included in here are a small set of other
things:
- kobject logging improvements
- cacheinfo improvements and updates
- obligatory fw_devlink updates and fixes
- documentation updates
- device property cleanups and const * changes
- firwmare loader dependency fixes.
All of these have been in linux-next for a while with no reported
problems.
