Not really. It was just assumption. It seems you are right, they are just
ignored silently. But item 2 is still relevant and it was actually confused
me when I tried to figure out MTD configuration for my platform.
Anyway, garbage should be taken out from time to time.

> Seems like the kind of change that can only be reviewed by a script.

Good point. Because these patches were done by script to start with.
Anyway, I reviewed result patches manually to be completely sure.
You can write verifying script though, if you need to, it wouldn't take
more than 2 minutes (it takes one-liner, actually).

Maybe they are. But they still in place, and why it's so, we should
maintain them up-to-date. Ideally, this kind of work should be done by
someone who introduces changes into Kconfig files. So I just fixed
that oversight.
