From 5095526faf38472bf04af919797a1f01a0ccb558 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Mon, 4 Mar 2013 06:45:33 +0000 Subject: [PATCH] Thermal: rcar: Convert to devm_ioremap_resource() Use the newly introduced devm_ioremap_resource() instead of devm_request_and_ioremap() which provides more consistent error handling. devm_ioremap_resource() provides its own error messages; so all explicit error messages can be removed from the failure code paths.
