    Subject[ 137/221] ALSA: hda - Disable runtime D3 for Intel CPT & co
    Date
    3.7-stable review patch.  If anyone has any objections, please let me know.

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

    From: Takashi Iwai <tiwai@suse.de>

    commit d7dab4dbbb2d1b0c903378d6bade2e4ae161804e upstream.

    We've got a few bug reports that the runtime D3 results in the dead
    HD-audio controller. It seems that the problem is in a deeper level
    than the sound driver itself, so as a temporal solution, disable the
    feature for these controllers again.
