From e8fa49b5d974846d367b103edc026c4d2b90ebfd Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Sun, 21 May 2017 01:19:39 +0000 Subject: [PATCH] drm/vgem: Fix return value check in vgem_init() In case of error, the function platform_device_register_simple() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
