From 0859ffc3b3cb673ac1d3f33b0265cf60d1e3836d Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 31 Oct 2013 15:50:55 +0800 Subject: watchdog: rt2880_wdt: fix return value check in rt288x_wdt_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().
