From: Dan Carpenter Date: Wed, 26 Nov 2014 14:06:49 +0000 (+0300) Subject: USB: adutux: NULL dereferences on disconnect X-Git-Tag: v3.2.67~112 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=27d0332283795d69f61a18aa1d758cfa528e8800;p=pandora-kernel.git 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.
