The kernel driver for the embedded controller exposes it as `/sys/class/leds/platform::mute` with trigger set to `audio-mute`. At the same time the hardware toggles the LED state when the mute key is pressed (independent of the real audio state) giving a fake suggestion of things working correctly. This series properly attaches the speaker mute state to this LED. To be functional, it depends on a kernel driver change for the speaker amplifier exposing a mute control knob. All handling has been implemented in a way, that using a kernel without this feature will continue to work as before.
