[alsa-devel] [PATCH 04/15] ALSA: hda - Clear the power-saving states properly at reset

[Takashi Iwai]

Some power-saving states have been left unchanged in
snd_hda_codec_reset(), and this is a potential danger because the
function may be called in various situations including the continuous
operation after that call.
