Remove unneeded error handling on the result of a call to platform_get_resource when the value is passed to devm_ioremap_resource.
The Coccinelle semantic patch that makes this change is as follows:
// <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>
