Ricardo Ribalda c775d4ff02 media: imon: Fix race getting ictx->lock 
[ Upstream commit 24147897507cd3a7d63745d1518a638bf4132238 ]

Lets fix a race between mutex_is_lock() and mutex_lock().

<-mutex is not locked
if (!mutex_is_locked(&ictx->lock)) {
	unlock = true; <- mutex is locked externaly
	mutex_lock(&ictx->lock);
}

Let's use mutex_trylock() that does mutex_is_lock() and mutex_lock()
atomically.

Fix the following cocci warning:
drivers/media/rc/imon.c:1167:1-7: preceding lock on line 1153

Fixes: 23ef710e1a6c ("[media] imon: add conditional locking in change_protocol")
