From: Dan Carpenter Date: Wed, 26 Nov 2014 14:06:49 +0000 (+0300) Subject: USB: adutux: NULL dereferences on disconnect X-Git-Tag: v3.12.37~4 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fdcc2a15ec6d4c4d7ef5562e92b2b83323e24106;p=platform%2Fkernel%2Flinux-stable.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.
