The div loop uses reassign and reuse parent_rate, which causes
the parent rate reference to be wrong after the first loop, the
resulting clock becomes incorrect for div != 1.

AFAIU, today it's possible to update a UBI partition via DFU with a new UBI

- It's no possible to have a volume-grained upgrade (per UB
