Public bug reported: [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.
