arch/arm/plat-pxa/dma.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> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: Eric Miao <eric.y.miao@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
