The Magic Mouse, generations 1 and 2, doesn't have a physical scroll
wheel, instead, the REL_WHEEL and REL_HWHEEL events are emulated
when sliding a finger on the surface of the mouse.
However, the smooth movement of the finger is transformed into a step
based scroll on the screen, leading to a suboptimal user experience.
Emulate high-resolution scroll by sending REL_WHEEL_HI_RES and
REL_HWHEEL_HI_RES events so the scroll on the screen is closer to the
finger movement.

The power supply states of discharging, charging, full, etc, represent
state of charging, not the capacity level of the battery (for which
we have a separate property). Current HID usage tables to not allow
for expressing charging state of the batteries found in generic
styli, so we should simply assume that the battery is discharging
even if current capacity is at 100% when battery strength reporting
is done via HID interface. In fact, we were doing just that before
commit 581c448476.
This change helps UIs to not mis-represent fully charged batteries in
styli as being charging/topping-off.

ISH IPC driver uses asynchronous workqueue to do resume now, but there is
a potential timing issue: when child devices resume before bus driver, it
will cause child devices resume failed and cannot be recovered until
reboot. The current implementation in this case do wait for IPC to resume
but fail to accommodate for a case when there is no ISH reboot and soft
resume is taking time. This issue is apparent on Tiger Lake platform with
5.11.13 kernel when doing suspend to idle then resume(s0ix) test. To
resolve this issue, we change ISHTP HID client to use asynchronous resume
callback too. In the asynchronous resume callback, it waits for the ISHTP
resume done event, and then notify ISHTP HID client link ready.

Getting a report (e.g. feature report) from a device requires us to send
a request indicating which report we want to retrieve and then waiting
for the corresponding response containing that report. We already
provide the response structure to the request call, but the request
isn't marked as a request that expects a response. Thus the request
returns before we receive the response and the response buffer indicates
a zero length response due to that.
This essentially means that the get-report calls are broken and will
always indicate that a report of length zero has been read.
Fix this by appropriately marking the request.

This commit fixes a freeze on insertion of a Guitar Hero Live PS3/WiiU
USB dongle. Indeed, with the current implementation, inserting one of
those USB dongles will lead to a hard freeze. I apologize for not
catching this earlier, it didn't occur on my old laptop.
While the issue was isolated to memory alloc/free, I could not figure
out why it causes a freeze. So this patch fixes this issue by
simplifying memory allocation and usage.
We remind that for the dongle to work properly, a control URB needs to
be sent periodically. We used to alloc/free the URB each time this URB
needed to be sent.
With this patch, the memory for the URB is allocated on the probe, reused
for as long as the dongle is plugged in, and freed once the dongle is
unplugged.

configuring encryption for the keyboard wireless link.
Now there also is a Linux tool for setting this up:
https://gitlab.freedesktop.org/jwrdegoede/logitech-27mhz-keyboard-encryption-setup
Once a keyboard is paired in encrypted mode, it will no longer work with
any receiver other then the receiver it was paired with.
If a user accidentally tries to pair another keyboard with the receiver
with which a keyboard has been paired in encrypted mode, then the receiver
looses the encryption key and the originally paired keyboard will no longer
work with either that receiver, or another receiver until the keyboard's
encryption key is rewritten by another encrypted mode pairing using the
tool. Or until it is reset by following a special reset procedure.
This commit adds 3 new log messages related to 27 MHz keyboard link
encryption to the Logitech dj / hidpp drivers:
1. An info level message when keyboard encryption is being used
2. A warning message when keyboard encryption is not used
3. An error message when the encryption key has been lost and the
keyboard will not work because of this
Messages 2. and 3. contain a link to the userspace tool to setup the
encryption. The linked page also contains instructions to clear the key
(without needing the tool) to help a user recover from the keyboard not
working in case 3.

Just like the K12A the Dell K15A keyboard-dock has problems with
get_feature requests. This sometimes leads to several
"failed to fetch feature 8" messages getting logged, after which the
touchpad may or may not work.
Just like the K15A these errors are triggered by undocking and docking
the tablet.
There also seem to be other problems when undocking and then docking again
in quick succession. It seems that in this case the keyboard-controller
still retains some power from capacitors and does not go through a
power-on-reset leaving it in a confuses state, symptoms of this are:
1. The USB-ids changing to 048d:8910
2. Failure to read the HID descriptors on the second (mouse) USB intf.
3. The touchpad freezing after a while
These problems can all be cleared by undocking the keyboard and waiting
a full minute before redocking it. Unfortunately there is nothing we can
do about this in the kernel.

The Saitek X65 joystick has a pair of axes that were used as mouse
pointer controls by the Windows driver. The corresponding usage page is
the Game Controls page, which is not recognized by the generic HID
driver, and therefore, both axes get mapped to ABS_MISC. The quirk makes
the second axis get mapped to ABS_MISC+1, and therefore made available
separately.

Action of unbinding driver from a device is not cancellable and should not
fail, and driver core does not pay attention to the result of "remove"
method, therefore using down_interruptible() in hid_device_remove() does

Older ROG keyboards emit a similar stream of bytes to the new
N-Key keyboards and require filtering to prevent a lot of
unmapped key warnings showing. As all the ROG keyboards use
QUIRK_USE_KBD_BACKLIGHT this is now used to branch to filtering
in asus_raw_event.

A number of USB keyboards, using the Semitek firmware, are capable of
handling arbitrary N-key rollover, but due to a buggy report
descriptor, keys beyond the sixth cannot be detected by the generic
HID driver.
There are numerous hardware variants sold by several vendors, mostly
using generic names like "GK61" for the 61-key version. These
keyboards are sometimes known collectively as the "GK6X" series.
The keyboard has three USB interfaces. Interface 0 uses the standard
HID boot protocol, limited to eight modifier keys and six normal keys;
interface 2 uses a custom report format that permits any number of
keys. If more than six keys are pressed simultaneously, the first six
are reported via interface 0 while subsequent keys are reported via
interface 2.
(Interface 1 uses a custom protocol for reprogramming the keyboard;
this can be controlled through userspace tools and is not of concern
for the present driver.)
The report descriptor for interface 2, however, is incorrect (for
report ID 0x04, the input field is marked as "array" rather than
"variable".) The descriptor appears to be correct in other respects,
so we simply replace the incorrect byte before parsing the descriptor.
