From 9a4864c897549e048b582372eca36e967b87784c Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 30 Oct 2013 11:09:15 +0800 Subject: gpio: tb10x: fix return value check in tb10x_gpio_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(). Also remove the dev_err call to avoid redundant error message.
