Jaroslav Kysela cb17fe0045 ALSA: control - add sysfs support to the LED trigger module 
Create SYSFS/devices/virtual/sound/ctl-led tree
(with SYSFS/class/sound/ctl-led symlink).

  speaker/
    +-- mode
    +-- brightness
  mic/
    +-- mode
    +-- brightness

Copy the idea from the HDA driver and allow to set the audio
LEDs based on the various modes:

- follow mute
- follow moute (inverted to follow mute)
- off
- on

Also, the actual LED state is exposed.
