From: Julia Lawall <Julia.Lawall@lip6.fr>
Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource.
A debugging statement in the error-handling code is removed as well, as it doesn't seem to give any more information than devm_ioremap_resource already gives.
A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ expression pdev,res,n,e,e1; expression ret != 0; identifier l; @@
- res = platform_get_resource(pdev, IORESOURCE_MEM, n); ... when != res - if (res == NULL) { ... \(goto l;\|return ret;\) } ... when != res + res = platform_get_resource(pdev, IORESOURCE_MEM, n); e = devm_ioremap_resource(e1, res); // </smpl>
