The situation fixed here is:

After bootup the partitioning information for mtd devices exists in both
locations (cdev->partitions and cdev->mtd->partitions). An interactive
addpart only adds the the latter. This patch fixes the of fixup to also

In the described error case the partition added to the bootup layout
(defined in the dtb) doesn't make it into the device tree provided to
