So, when CONFIG_MTD_PARTITIONED_MASTER is not set and a driver like MTDRAM
does mtd_device_register(mtd, NULL, 0) we end up here with partitioned = false,
and allocate just a master device but no real mtd because with zero
parts the mtd_device_parse_register() function will not call add_mtd_device(). :-(
