Subject: [PATCH] drivers/block/drbd/drbd_receiver.c: 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>
@@
expression x,y;
statement S;
@@
x = \(kmalloc\|kcalloc\|kzalloc\)(...);
(
if ((x) == NULL) S
|
if (
- y
+ x
== NULL)
S
)
// </smpl>
