Subject: [PATCH 3.16.y-ckt 049/216] cdc-acm: memory leak in error case

3.16.7-ckt4 -stable review patch.  If anyone has any objections, please let me know.

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

From: Oliver Neukum <oneukum@...e.de>

commit d908f8478a8d18e66c80a12adb27764920c1f1ca upstream.

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