This patch adds a new LED trigger for coupling the audio mixer change with the LED on laptops or other devices. Currently there are two trigger types, "audio-mute" and "audio-micmute".
The audio driver triggers the LED brightness change via ledtrig_audio_set() call with the proper type (either mute or mic-mute). OTOH, the consumers may call ledtrig_audio_get() for the initial brightness value that may have been set by the audio driver beforehand.
This new stuff will be used by HD-audio codec driver and some platform drivers (thinkpad_acpi and dell-laptop, also upcoming huawei-wmi).

Only on of above is needed, I think you meant module.h.
