[PATCH 0/2] Add ASUS ExpertBook mute LED support

[patryk . dankow]

From: Patryk Dańków <patryk.dankow@xxxxxxxxxxxxxx>

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.
