From 147fd9d6bbb6b4bf1c320089494c0cb1bf1636a2 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 14 Jan 2015 09:10:00 +0800 Subject: phy: fix return value check in armada375_usb_phy_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().
