Subject[PATCH 3.16.y-ckt 119/135] USB: adutux: NULL dereferences on disconnect
Date
3.16.7-ckt6 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

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')
