    Subject[PATCH 4.2.y-ckt 091/218] ALSA: hda - Apply reboot D3 fix for CX20724 codec, too
    Date
    4.2.8-ckt7 -stable review patch.  If anyone has any objections, please let me know.

    ---8<------------------------------------------------------------

    From: Takashi Iwai <tiwai@suse.de>

    commit 56dc66ff1c6d71f9a38c4a7c000b72b921fe4c89 upstream.

    Just like CX20722, CX7024 codec also requires the power down at reboot
    in order to reduce the noise at reboot/shutdown.
