    ALSA: hda - Introduce "Headset Mic" name · a385d97b
    David Henningsson authored
    Headset mic jacks, i e TRRS style jacks with Headphone Left,
    Headphone Right, Mic and GND signals, are becoming increasingly
    common and are now being shipped by several manufacturers.
    
    Unfortunately, the HDA specification does not give us any hint
    of whether a Mic pin belongs to such a jack or not, but it would
    still be helpful for the user to know (especially if there is one
    TRS Mic jack and one TRRS headset jack).
    
    This new fixup causes the first (non-dock, non-internal) mic to
    be a headset mic jack. The algorithm can be later refined if needed.
