arch/sh/mm: Move a dereference below a NULL test
If the NULL test is necessary, then the dereference should be moved below the NULL test. The semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/). // <smpl> @disable is_null@ identifier f; expression E; identifier fld; statement S; @@ + if (E == NULL) S f(...,E->fld,...); - if (E == NULL) S @@ identifier f; expression E; identifier fld; statement S; @@ + if (!E) S f(...,E->fld,...); - if (!E) S // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Paul Mundt <lethal@linux-sh.org>
