Subject: ALSA: hda - Fix leftover codec->power_transition
X-Git-Tag: v3.6-rc3~14^2~1
X-Git-Url: http://git.kernel.org/?p=linux%2Fkernel%2Fgit%2Ftorvalds%2Flinux.git;a=commitdiff_plain;h=535b6c51fe8293c88ce919cdfc4390c67a1cb6d1
ALSA: hda - Fix leftover codec->power_transition
When the codec turn-on operation is canceled by the immediate
power-on, the driver left the power_transition flag as is.
This caused the persistent avoidance of power-save behavior.
