You have to embed struct class_device to mtd_info and use
constructor_of(). Read LDD3. LDD3 does not contain much information
about the class_device stuff, but the techniques used in "struct device"
stuff are the same.

Why don't you use the "struct device/device_driver/bus" stuff which
would be natural?
