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.
