V4L/DVB: drivers/media/video: move dereference after NULL test
In quickcam_messenger.c, if the NULL test on uvd is needed, then the
dereference should be after the NULL test.
In vpif_display.c, std_info is initialized to the address of a structure
field. This seems unlikely to be NULL. Test std_info->stdid instead.
In saa7134-alsa.c, the function is only called from one place, where the
chip argument has already been dereferenced. On the other hand, if it
should be kept, then card should be initialized after it.
A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):
