From 3295235fd70ed6d594aadee8c892a14f6a4b2d2e Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sat, 13 Aug 2016 01:28:24 +0000 Subject: usb: renesas_usbhs: gadget: fix return value check in usbhs_mod_gadget_probe() In case of error, the function usb_get_phy() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
