[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_FIXUP_CS35L41_I2C_2, but the regression possibility is very low since hda_fixup_thinkpad_acpi() could check if the quirk is suitable for the running machine. And we did test, all machines could work well.
