Try adding it and if it works send the patches? I think there is a disconnect. Right now device_get_match_data callbacks are part of fwnode_operations. I was proposing to add another optional device_get_match_data callback to 'struct bus_type' to allow individual buses control how match data is handled, before (or after) jumping into the fwnode-backed device_get_match_data callbacks.
