ALSA: hda - Shut up pins at power-saving mode with Conexnat codecs
Call snd_hda_shutup_pins() for power-saving and reboot-notifier in patch_conexant.c as well as other codecs. This will reduce the pop noise in power-save mode. Reference: bnc#624896 https://bugzilla.novell.com/show_bug.cgi?id=624896 Signed-off-by: Takashi Iwai <tiwai@suse.de>
