Hum, whenever we do change in the kconfig code, we like them to be part
of the patch series we have. See support/kconfig/README.buildroot for
details. In this case, indeed, the fix is already upstream. But still,
we would like to keep separated the base kconfig version (copied
as-is from the kernel) from any further modification we have made.

Thanks!
