The V4L2_ASYNC_MATCH_DEVNAME match criteria requires just a device name. So, it doesn't make sense to enclose those into structs, as the criteria can go directly into the union. That makes easier to document it, as we don't need to document weird senseless structs. At drivers, this makes even clearer about the match criteria.
