    ALSA: hda - Fix inconsistent Mic mute LED · 7fe30711
    Takashi Iwai authored
    The current code for controlling mic mute LED in patch_sigmatel.c
    blindly assumes that there is a single capture switch.  But, there can
    be multiple multiple ones, and each of them flips the state, ended up
    in an inconsistent state.
    
    For fixing this problem, this patch adds kcontrol to be passed to the
    hook function so that the callee can check which switch is being
    accessed.  In stac_capture_led_hook(), the state is checked as a
    bitmask, and turns on the LED when all capture switches are off.
