Clang warns that the address of a pointer will always evaluated as true in a boolean context.
drivers/media/pci/cx18/cx18-driver.c:1255:23: warning: address of 'cx->streams[i].video_dev' will always evaluate to 'true' [-Wpointer-bool-conversion] if (&cx->streams[i].video_dev) ~~ ~~~~~~~~~~~~~~~^~~~~~~~~ 1 warning generated.
Check whether v4l2_dev is null, not the address, so that the statement doesn't fire all the time. This check has been present since 2009, introduced by commit 21a278b85d3c ("V4L/DVB (11619): cx18: Simplify the work handler for outgoing mailbox commands")
