[PATCH 3.12 42/66] can: esd_usb2: fix memory leak on disconnect

[Jiri Slaby]

From: Alexey Khoroshilov <khoroshilov@xxxxxxxxx>

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

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

commit efbd50d2f62fc1f69a3dcd153e63ba28cc8eb27f upstream.

It seems struct esd_usb2 dev is not deallocated on disconnect. The patch adds
the missing deallocation.

Found by Linux Driver Verification project (linuxtesting.org).
