staging: [media] mn88472: simplify NULL tests
Author: Eva Rachel Retuya <eraretuya@gmail.com>
Replace direct comparisons to NULL i.e. 'x == NULL' with '!x' for
consistency. Coccinelle semantic patch used:
@@
identifier func;
expression x;
statement Z;
@@
x = func(...);
if (
(
+ !
x
- == NULL
|
+ !
- NULL ==
x
)
) Z
