    Subject[PATCH 3.14 061/100] ALSA: ALC283 codec - Avoid pop noise on headphones during suspend/resume
    Date
    3.14-stable review patch.  If anyone has any objections, please let me know.

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

    From: Harsha Priya <harshapriya.n@intel.com>

    commit b450b17c156e264bc44a198046d3ebaaef5a041d upstream.

    This patch sets the headphones mode to default before suspending
    which helps avoid the pop noise on headphones
