3.13.11-ckt12 -stable review patch. If anyone has any objections, please let me know.
------------------
From: Alexey Khoroshilov <khoroshilov at ispras.ru>
commit efbd50d2f62fc1f69a3dcd153e63ba28cc8eb27f upstream.
It seems struct esd_usb2 dev is not deallocated on disconnect. The patch adds
the missing deallocation.
