    ALSA: hda - Add power state filtering · 9419ab6b
    Takashi Iwai authored
    Add a hook to struct hda_codec for filtering the target power state of
    each widget when powering up/down.  The current hackish EAPD check is
    implemented as the default hook pointer, too.
    
    This allows codec drivers to implement own power filter.  In the
    upcoming changes, the generic parser will have the better power filter
    based on the active paths.
