-stable review patch. If anyone has any objections, please let us know.
------------------
From: Robert Hancock <[email protected]>
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.
