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.
