    Subject[ 04/62] ALSA: hda/conexant - Dont set HP pin-control bit unconditionally
    3.3-stable review patch.  If anyone has any objections, please let me know.

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

    From: Takashi Iwai <tiwai@suse.de>

    commit ca3649de026ff95c6f2847e8d096cf2f411c02b3 upstream.

    Some output pins on Conexant chips have no HP control bit, but the
    auto-parser initializes these pins unconditionally with PIN_HP.

    Check the pin-capability and avoid the HP bit if not supported.
