Bug description:
[SRU Justifications]
[Impact]
Audio miu 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.
[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 so we don’t
need the quirks anymore to get the amplifier drivers started. Cirrus claims it
should cover Machu, Lapaz and Colosseum on HP laptops.
