    Subject[ 027/108] ALSA: hda - Fix leftover codec->power_transition
    Date
    From: Greg KH <gregkh@linuxfoundation.org>

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

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

    From: Takashi Iwai <tiwai@suse.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.
