From 81455e72211e41972cca1d4686bc07b2e93b81e1 Mon Sep 17 00:00:00 2001 From: Julia Lawall Date: Wed, 14 Aug 2013 11:11:12 +0200 Subject: [PATCH] cpuidle-kirkwood.c: simplify use of devm_ioremap_resource() Remove unneeded error handling on the result of a call to platform_get_resource 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/) // @@ 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); // Signed-off-by: Julia Lawall Signed-off-by: Rafael J.
