From 00cf99ee00c9f1241359c8ee5ca9230318e27a57 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 25 Jun 2013 10:09:57 +0800 Subject: pwm: renesas-tpu: fix return value check in tpu_probe() In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
