The common code can now read, verify and fix meta-data copies while exposing one consistent structure to users. Only the .read_mdata() and .write_mdata() callbacks of fwu_mdata_ops are needed. Get rid of .get_mdata() .update_mdata() .get_mdata_part_num() .read_mdata_partition() and .write_mdata_partition() and also the corresponding wrapper functions.
