From cd5d58108e41b0edecc1e7a6468cbe06ce03be3f Mon Sep 17 00:00:00 2001 From: Wei Yongjun <yongjun_wei@trendmicro.com.cn> Date: Thu, 31 Oct 2013 15:51:38 +0800 Subject: MIPS: ralink: fix return value check in rt_timer_probe() In case of error, the function devm_request_and_ioremap() returns NULL pointer not ERR_PTR(). Fix it by using devm_ioremap_resource() instead of devm_request_and_ioremap().
