commit aa58fedb upstream. Make sure to check the number of endpoints to avoid accessing memory beyond the endpoint array should a device lack the expected endpoints. Note that, as far as I can tell, the gspca framework has already made sure there is at least one endpoint in the current alternate setting so there should be no risk for a NULL-pointer dereference here.
