    ALSA: hda - Allow codec-specific set_power_state ops · 4d7fbdbc
    Takashi Iwai authored
    The procedure for codec D-state change may have exceptional cases
    depending on the codec chip, such as a longer delay or suppressing D3.
    This patch adds a new codec ops, set_power_state() to override the system
    default function.  For ease of porting, snd_hda_codec_set_power_to_all()
    helper function is extracted from the default set_power_state() function.
    As an example, the Conexant codec-specific delay is removed from the
    default routine but moved to patch_conexant.c.
