Subject[PATCH 3.12 173/176] USB: adutux: NULL dereferences on disconnect
Date
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.

Fixes: 03270634e242 ('USB: Add ADU support for Ontrak ADU devices')
