To me these two new Kconfig symbols look pointless:
- they have no prompt, so one cannot set them manually;
- no other Kconfig symbol selects them;
- they do not default to 'y'.

I'm not aware of a way to set these symbols to 'y' outside of those
three. Is there perhaps a way for kconfig to set these symbols to 'y'
that I have missed?

Or do you expect to do one of these three things in a separate patch?

So I think this hunk is pointless.

Ditto.

Ditto (except for the help change, which still might make sense).

Thanks,
