ASoC: omap: 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. 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> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Jarkko Nikula <jarkko.nikula@bitmer.com> Signed-off-by: Mark Brown <broonie@linaro.org>
