The patch titled

has been removed from the -mm tree.  Its filename was
     arch-arm-plat-pxa-dmac-correct-null-test.patch

Subject: arch/arm/plat-pxa/dma.c: correct NULL test
From: Julia Lawall <julia@diku.dk>

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>
