[PATCH] USB: Small change to CPiA USB driver
Only one aspect of it is notable: The CPiA USB
driver calls usb_driver_release_interface() during its disconnect()
routine. That doesn't appear to be necessary, since it didn't call
usb_driver_claim_interface() beforehand and since the interface will be
released automatically when disconnect() returns.
