Yup, I end up with the above situation myself. Please try the patch

David, are mtdcore, mtdsuper, mtdpart (and I also noticed mtdbdi.c
in -mm kernel) supposed to be linked into the same module or are they
supposed to be built as separate modules?

If separate, we need to apply Rafal's patch and ensure MODULE_LICENSE
(at least) in all the above files.

If the same module, then please consider applying the patch below.

[PATCH] mtd: Makefile fix

We want drivers/mtd/{mtdcore, mtdsuper, mtdpart}.c to be built and linked
into the same mtd.ko module. Fix the Makefile to ensure this, and remove
duplicate MODULE_ declarations in mtdpart.c, as mtdcore.c already has them.
