drivers/dma/pl330.c: add missing iounmap
Add missing iounmap in error handling code, in a case where the function already preforms iounmap on some other execution path. This patch additionally adds calls to clk_disable and clk_put. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e; statement S,S1; int ret; @@ e = \(ioremap\|ioremap_nocache\)(...) ... when != iounmap(e) if (<+...e...+>) S ... when any when != iounmap(e) *if (...) { ... when != iounmap(e) return ...; } ... when any iounmap(e); // </smpl> Signed-off-by: NJulia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: NVinod Koul <vinod.koul@linux.intel.com>
