Subject: [PATCHv2 0/2] Apple Magic Keyboard Backlight

This patchseries adds support for the internal keyboard backlight of
Macs with Apple's "Magic" keyboard (MacBookPro16,* and MacBookAir9,1),
and also documents what names should be used for keyboard backlight
leds in Documentation/leds/well-known-leds.txt.

A previous version of this patch was sent alongside some other drivers
here[1] but for v2 I'm submitting it separately to make upstreaming
easier.

v1->v2:
- drop unneeded remove function
- combine set functions
- add missing header inclusions
- avoid char as argument in favour of u8
- handful of style/formatting fixes
- use standard led name ":white:kbd_backlight"
- rename USAGE_MAGIC_BL to HID_USAGE_MAGIC_BL
- New patch documenting preferred keyboard backlight names
