From dc81bed127a93e20d2100624273a27369738ffc7 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Mon, 3 Sep 2007 09:36:36 +0200 Subject: [ALSA] hda-codec - Fix wrong pin-setup at resume of STAC codecs The resume procedure for STAC codecs overrides the cached values and results in the wrong (reset) PIN state. The patch gets rid of the overriding part and simplifies the resume.
