This is a three part series which does the following:
- Clean init sequence, fix the keyboard of the Z13 (touchpad,fan button)
- Unifies backlight handling to happen under asus-wmi so that all Aura
devices have synced brightness controls and the backlight button works
properly when it is on a USB laptop keyboard instead of one w/ WMI.
- Adds RGB support to hid-asus, solid colors only, and for the ROG Ally
units and the Asus Z13 2025 first.
For context, see cover letter of V1.
The last two patches are still a bit experimental, the rest is getting to
be pretty stable by now. I will test my Ally in the weekend. Also, I am
not a fan of the asus-0003:0B05:1A30.0001-led name, so suggestions would
be appreciated.

V1: https://lore.kernel.org/all/20250319191320.10092-1-lkml@xxxxxxxxxxx/
Changes since V1:
- Add basic RGB support on hid-asus, (Z13/Ally) tested in KDE/Z13
- Fix ifdef else having an invalid signature (reported by kernel robot)
- Restore input arguments to init and keyboard function so they can
be re-used for RGB controls.
- Remove Z13 delay (it did not work to fix the touchpad) and replace it
with a HID_GROUP_GENERIC quirk to allow hid-multitouch to load. Squash
keyboard rename into it.
- Unregister brightness listener before removing work queue to avoid
a race condition causing corruption
- Remove spurious mutex unlock in asus_brt_event
- Place mutex lock in kbd_led_set after LED_UNREGISTERING check to avoid
relocking the mutex and causing a deadlock when unregistering leds
- Add extra check during unregistering to avoid calling unregister when
no led device is registered.
- Temporarily HID_QUIRK_INPUT_PER_APP from the ROG endpoint as it causes
the driver to create 4 RGB handlers per device. I also suspect some
extra events sneak through (KDE had the @@@@@@).
