From 2e4924628ad957f702631a7a049c586a780f00f8 Mon Sep 17 00:00:00 2001 From: Maxim Levitsky Date: Mon, 3 Sep 2007 15:26:57 +0200 Subject: [PATCH] [ALSA] hda-intel - fix a race in dynamic power managment codec->power_transition is supposed to be true while codec is going to be shut off if in the mean time somebody calls snd_hda_power_up, hda_power_work will not shut down the codec, but nether will clear codec->power_transition, thus it stays on forever. Fix this.
