From 8c0614ca312c847ca5409ea11c39434dec69631d Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sat, 6 Feb 2016 22:57:06 +0800 Subject: usb: chipidea: fix return value check in ci_hdrc_pci_probe() In case of error, the function usb_phy_generic_register() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
