The COMEDI_TESTS_NI_ROUTES option currently selects NI_ROUTING, which doesn't exist. It should be selecting COMEDI_NI_ROUTING. Fix it. Selecting COMEDI_TESTS_NI_ROUTES without COMEDI_NI_ROUTING resulted in the following build errors: ERROR: modpost: "ni_lookup_route_register" [drivers/staging/comedi/drivers/tests/ni_routes_test.ko] undefined!
