+Subject: [PATCH] MIPS: ath79: simplify platform_get_resource_byname/devm_ioremap_resource
+
+Remove unneeded error handling on the result of a call to
+platform_get_resource_byname when the value is passed to devm_ioremap_resource.
+
+A simplified version of the semantic patch that makes this change is as
+follows: (http://coccinelle.lip6.fr/)
+
+// <smpl>
+@@
+expression pdev,res,e,e1;
+expression ret != 0;
+identifier l;

+
+  res = platform_get_resource_byname(...);
+- if (res == NULL) { ... \(goto l;\|return ret;\) }
+  e = devm_ioremap_resource(e1, res);
+// </smpl>
