From: Dan Carpenter <dan.carpenter@oracle.com>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit fc625960edecfb57e62c2975d1f155155e28e6ba upstream.
Both "dev->udev" and "interface->dev" are NULL. These printks are not very interesting so I just deleted them.
