Bug description:
[SRU Justifications]
[Impact]
Audio mic mute function works OK but the LED does not toggle
accordingly.
[Fix]
This requires the upstream commit
https://lore.kernel.org/all/20240829161114.140938-1-sim...@opensource.cirrus.com/
from Cirrus. And additional quirk for specific HP SSIDs are required for
working mic-mute led.
[Test Case]
1. Boot up the HP ZBook series laptops with Audio codec + Cirrus amplifier
2. Press the Mic Mute function key (F9) and check the mic mute function
3. Check if the LED (on F9) is ON when Mic Mute, and OFF when Mic not muted.
[Where problems could occur]
The auto-detection patch is looking for cs35l56 variants in ACPI. Cirrus
claims it should cover Machu, Lapaz and Colosseum on HP laptops to get the HDA
codec automatically work with the amplifier. The only thing need to be quirked
is for mic-mute LED. It only applies on particular HP models and shouldn't
introduce regression.
