    Subject[09/35] ath9k: Fix suspend/resume when no interface is UP
    2.6.32-longterm review patch.  If anyone has any objections, please let us know.

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

    From: Rajkumar Manoharan <rmanohar@qca.qualcomm.com>

    commit c31eb8e926835582cd186b33a7a864880a4c0c79 upstream.

    When no interface has been brought up, the chip's power
    state continued as AWAKE. So during resume, the chip never
    been powered up.
