Subject: [PATCH 3/3] [media] camss-csid: Adjust a null pointer check in two
 functions

From: Markus Elfring <elfring@...rs.sourceforge.net>

The script "checkpatch.pl" pointed information out like the following.

Comparison to NULL could be written "!format"

Thus fix the affected source code places.
