Subject: [PATCH 11/18] V4L/DVB (4740): Fixed an if-block to avoid floating
	with debug-messages


From: Enrico Scholz <enrico.scholz@...ormatik.tu-chemnitz.de>

The dbgarg() macro in videodev.c contains some printk() statements
where only the first one is influenced by an if-statement. This causes
floating with debug-messages which is fixed by this patch by adding a
'{ ... }' pair.
