3.16.7-ckt5 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Mario Schuknecht <mario.schuknecht@xxxxxxxxxxxxxxx>
commit b44be2462dbe3e23f0aedff64de52a1e8e47a1cd upstream.
Commit 3b74c73f8d6f053f422e85fce955b61fb181cfe7 switched over to memdup_user()
in ep_write() function and removed kfree (kbuf).
memdup_user() function allocates memory which is never freed.
Fixes: 3b74c73 (usb: gadget: inode: switch over to memdup_user())
