From fb8d1a344dbe963f16249d07eee8415e93f9f3c2 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 10 Nov 2009 16:02:29 +0100 Subject: ALSA: hda - Add reboot notifier to each codec Add reboot notifier to each codec so that it can do some workarounds needed for reboot. So far, patch_sigmatel.c calls its shutup routine for avoiding noises at reboot on some HP machines.
