    ALSA: hda - Fix missing Mic Boost controls for VIA codecs · d045c5dc
    Takashi Iwai 提交于
    Some VIA codecs like VT1708S have Mic boost amps in the mic pins but
    they aren't exposed in the capability bits.  In the past driver code,
    we override the pin caps and create mic boost controls forcibly.
    While transition to the generic parser, we lost the mic boost controls
    although the pin caps are still overridden, because the generic parser
    code checks the widget caps, too.
    
    So this patch adds a new helper function to allow the override of the
    given widget capability bits, and makes VIA codecs driver to add the
    missing input-amp capability bit.
