Takashi Iwai 5b1ed7df01 ALSA: control - add generic LED API 
This patchset tries to resolve the diversity in the audio LED
 control among the ALSA drivers. A new control layer registration
 is introduced which allows to run additional operations on
 top of the elementary ALSA sound controls.
 
 A new control access group (three bits in the access flags)
 was introduced to carry the LED group information for
 the sound controls. The low-level sound drivers can just
 mark those controls using this access group. This information
 is not exported to the user space, but user space can
 manage the LED sound control associations through sysfs
 (last patch) per Mark's request. It makes things fully
 configurable in the kernel and user space (UCM).
 
 The actual state ('route') evaluation is really easy
 (the minimal value check for all channels / controls / cards).
 If there's more complicated logic for a given hardware,
 the card driver may eventually export a new read-only
 sound control for the LED group and do the logic itself.
 
 The new LED trigger control code is completely separated
 and possibly optional (there's no symbol dependency).
 The full code separation allows eventually to move this
 LED trigger control to the user space in future.
 Actually it replaces the already present functionality
 in the kernel space (HDA drivers) and allows a quick adoption
 for the recent hardware (ASoC codecs including SoundWire).

 The sound driver implementation is really easy:
 
 1) call snd_ctl_led_request() when control LED layer should be
    automatically activated
    / it calls module_request("snd-ctl-led") on demand /
 2) mark all related kcontrols with
         SNDRV_CTL_ELEM_ACCESS_SPK_LED or
         SNDRV_CTL_ELEM_ACCESS_MIC_LED
