From: Jiri Slaby
Date: Thu Jan 29 2015 - 04:56:32 EST


From: Oliver Neukum <oneukum@xxxxxxx>

3.12-stable review patch. If anyone has any objections, please let me know.

===============

commit d908f8478a8d18e66c80a12adb27764920c1f1ca upstream.

If probe() fails not only the attributes need to be removed
but also the memory freed.
