Subject[PATCH 3/9] V4L/DVB (5021): Cx88xx: Fix lockup on suspend
Date

From: Robert Hancock <hancockr@shaw.ca>

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.
