From 634608f27acd098b245ca6fe60e06701185eb170 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 7 Jan 2014 16:56:35 +0800 Subject: misc: genwqe: fix return value check in genwqe_device_create() In case of error, the function device_create_with_groups() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
