This series adds speaker mute LED support for the ASUS ExpertBook
PM3406CKA.

The first patch adds the ASUS WMI mute LED endpoint and registers it as
the platform::mute LED using the audio-mute trigger.

The second patch enables vmaster mute LED handling for the PM3406CKA in
the Realtek HDA codec driver. The existing CS35L41 I2C fixup is retained
by chaining the new fixup to it.

The WMI device ID 0x0004001c is present in the PM3406CKA DSDT and is also
used by GHelper for controlling the same LED.

Tested on ASUS ExpertBook PM3406CKA.

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.

FYI [if applicable to your patch], as per Linus' policy change, also
fixes are mostly routed through for-next unless the fix is for a
commit introduced in the most recent cycle or is clearly a regression
fix.
