drivers/block/drbd: 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> Signed-off-by: Philipp Reisner <philipp.reisner@linbit.com>
