From 27d0332283795d69f61a18aa1d758cfa528e8800 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 26 Nov 2014 17:06:49 +0300 Subject: [PATCH] USB: adutux: NULL dereferences on disconnect commit fc625960edecfb57e62c2975d1f155155e28e6ba upstream. Both "dev->udev" and "interface->dev" are NULL. These printks are not very interesting so I just deleted them.
