From 97eba3260e7c4e65e1c085301c2330110bd6aa2b Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Mon, 26 Mar 2018 06:43:57 +0000 Subject: usb: roles: Fix return value check in intel_xhci_usb_probe() In case of error, the function devm_ioremap_nocache() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
