If anyone has any objections, please let me know. ------------------ From: Takashi Iwai commit d183b4fc463489b6bbe05c99afa0257a6fe578eb upstream. snd_hda_codec_reset() is called either in resetting the whole setup at error paths or hwdep clear/reconfig sysfs triggers. But all of these don't assume that the power has to be off, rather they want to keep the power state unchanged (e.g. reconfig_codec() calls the power up/down by itself). Thus, unconditionally clearing the power state in snd_hda_codec_reset() leads to the inconsistency, confuses the further operation. This patch gets rid of the lines doing that bad thing.
