Bug Description
The fix is already in the upstream kernel stable-v5.17, no need to
send this patch to oem-5.17 and unstable kernels.
[Impact]
After we apply the cs35l41 s-codec patchset to the oem-5.14 and jammy
kernels, the mute led can't work anymore.
[Fix]
Backport a patch from mainline kernel to fix this regression
[Test]
boot the patched kernel, press mute hotkey, the speaker is muted
and the mute led is on, press the mute hotkey again, the speaker
is unmuted and the mute led is off.
[Where problems could occur]
After merging this patch, it is possible to affect the machines which
apply the ALC287_
is very low since hda_fixup_
is suitable for the running machine. And we did test, all machines
could work well.
