This mechanism needs astruct device to work so fwnode-based lookup with no device associatedcurrently causes a NULL-pointer deference.\nAdding this functionality will require a larger rework and it has neverworked anyway so add a check that allows the kernel to gracefully handlethis situation with an error ahead of implementing that functionality asa new
