[SRU][Oracular][PATCH 0/1] hid-asus: use hid for brightness control

[Mitchell Augustin]

BugLink: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2089113

[Impact]

The brightness of some ASUS ROG laptop keyboards cannot be adjusted
without this patch.

[Test case]

I verified that this patch applies cleanly to the Oracular kernel
at Ubuntu-6.11.0-9.9 and resolves the bug on my laptop
(Asus ROG GA503RM). I observed no regressions. This can be verified
on any similar model of laptop.

[Fix]

On almost all ASUS ROG series laptops the MCU used for the USB keyboard
also has a HID packet used for setting the brightness. This is usually
the same as the WMI method. But in some laptops the WMI method either
is missing or doesn't work, so we should default to the HID control.


[Regression potential]

I do not expect any regressions since this only touches parts of
asus-wmi and hid-asus that are covered by my test case, which worked
as intended.
