V4L/DVB (5021): Cx88xx: Fix lockup on suspend
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. Signed-off-by: Robert Hancock <hancockr@shaw.ca> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
