    Subject[patch 01/21] V4L: cx88: Fix lockup on suspend
    -stable review patch.  If anyone has any objections, please let us know.

    Suspending with the cx88xx module loaded causes the system to lock up
    because the cx88_audio_thread kthread was missing a try_to_freeze()
    call, which caused it to go into a tight loop and result in softlockup
    when suspending. Fix that.

    (cherry picked from commit a96afb3e9428f2e7463344f12dbc85faf08e2e09)
