clk: sunxi: fix devm_ioremap_resource error detection code
devm_ioremap_resource returns an ERR_PTR value, not NULL, on failure. A simplified version of the semantic match that finds this problem is as follows: // <smpl> @@ expression e,e1; statement S; @@ *e = devm_ioremap_resource(...); if (!e1) S // </smpl> Signed-off-by: Himangi Saraogi <himangi774@gmail.com> Acked-by: Julia Lawall <julia.lawall@lip6.fr> Acked-by Boris BREZILLON <boris.brezillon@free-electrons.com> Signed-off-by: Mike Turquette <mturquette@linaro.org>
