this is an unrelated change and should be removed. I guess this was
intentional by Stefan. If not, please submit a separate patch for that.

you should add the vendor name, e.g.

a lot of "is not set" entries. Did you generate this config with "make
savedefconfig"?

you should not enable features which the patch set don't support yet. I
don't know about USB because you didn't mentioned it anywhere. But FAT
or block devices are obviously left-overs from your MMC/SD experiments ;)
