From 697c373e34613609cb5450f98b91fefb6e910588 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 30 Jul 2010 11:28:02 +0200 Subject: 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.
