Bug description:
[Impact]
Some systems use a special hotkey to mute speaker audio. On systems using
CS35L41 HDA which have this hotkey, add a mechanism which uses ACPI
notifications to detect whether the hotkey is triggered to switch the mute
state.
[Fix]
Backport the fix from Cirrus on linux-next
https://lore.kernel.org/alsa-devel/87fs36egnv.wl-ti...@suse.de/T/#t.
[Test Case]
1. Power on the machine with CS35L41 HDA and the speaker mute hotkey.
2. Verify the audio functions
3. Verify if the speaker can be mute/unmute by the hotkey.
[Where problems could occur]
Only affect specific laptops with the CS35L41 HDA and the speaker mute hotkey
on keyboard. The impact is restricted.
