From: lizf

From: Alexey Khoroshilov <khoroshilov@xxxxxxxxx>

3.4.106-rc1 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.
