Not having much luck with this... for some reason the mtd_info struct passed
in doesn't have a name on its device, and I'm not sure why. It doesn't match
the mtd_info structs created from the partitions either. Can anyone shed
some light on this?

Not that I can see.
I'll fix things according to your other comments.
