Subject: [ 027/108] ALSA: hda - Fix leftover codec->power_transition

From: Greg KH <gregkh@...uxfoundation.org>

3.5-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Takashi Iwai <tiwai@...e.de>

commit 535b6c51fe8293c88ce919cdfc4390c67a1cb6d1 upstream.

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.
