    ALSA: hda - Re-add the lost fake mute support · a686ec4c
    Takashi Iwai authored
    Yet another regression by the transition to regmap cache; for better
    usability, we had the fake mute control using the zero amp value for
    Conexant codecs, and this was forgotten in the new hda core code.
    
    Since the bits 4-7 are unused for the amp registers (as we follow the
    syntax of AMP_GET verb), the bit 4 is now used to indicate the fake
    mute.  For setting this flag, snd_hda_codec_amp_update() becomes a
    function from a simple macro.  The bonus is that it gained a proper
    function description.
