staging: media: atomisp: Replace NULL comparison.

Linux kernel mirror (for testing) git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

kernel os linux

Replaced x == NULL with !x, by using the following coccinelle script:

@disable is_null@
expression e;
@@

-e==NULL
+!e

This patch fixes the checkpatch issue.
