From 05a27928f37b31ea8b844e3b0c623d7f46451145 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Sun, 22 Sep 2013 14:42:25 -0300 Subject: [PATCH] crypto: dcp - Use devm_ioremap_resource() Using devm_ioremap_resource() can make the code simpler and smaller. When devm_ioremap_resource() is used there is no need to explicitely check the error returned by platform_get_resource().
