V4L/DVB (13954): Correct NULL test
Test the just-allocated value for NULL rather than some other value.
The semantic patch that makes this change is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@r@
identifier f;
@@
f(...) { <+... return NULL; ...+> }
@@
expression *x;
expression y;
identifier r.f;
statement S;
@@
x = f(...);
(
if ((x) == NULL) S
|
if (
- y
+ x
== NULL)
S
)
// </smpl>
