From 84e819220468e989a0dde33bf1121888c5e749b1 Mon Sep 17 00:00:00 2001 From: Sachin Kamat Date: Mon, 4 Mar 2013 09:59:00 +0530 Subject: [PATCH] serial: tegra: 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.
