4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
commit e89e50ac35d9126907a436dabe70f9a8311b9981 upstream.
We should be checking for IS_ERR() instead of NULL because
drm_dev_alloc() returns error pointers.
Fixes: 45d59d704080 ("drm: Add new driver for MXSFB controller")
