Remove unneeded error handling on the result of a call to platform_get_resource_byname when the value is passed to devm_ioremap_resource.
In the case of omap-dmic.c, the error-handling code of devm_ioremap_resource is also corrected to include releasing the clock.
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>
