I think that's a bug in the Kconfig files that should be fixed
by enforcing the correct set of dependencies. I have not encountered
this in my randconfig builds (with a lot of other fixes applied)

In linux-next, CONFIG_VT cannot be disabled if CONFIG_EXPERT=n,
so this does not happen.

Changing the local config should not be required after fixing
the Kconfig files.
