Ok, so this is a bit nitpicky, but commit c7ef8221ca7d ("ice: use GNSS
subsystem instead of TTY") ends up doing odd things to kernel configs.

My local configuration suddenly grew this:

    CONFIG_ICE_GNSS=y

which is pretty much nonsensical.

The reason? It's defined as

    config ICE_GNSS
            def_bool GNSS = y || GNSS = ICE

and so it gets set even when both GNSS and ICE are both disabled,
because 'n' = 'n'.

Does it end up *mattering*? No. It's only used in the ICE driver, but
it really looks all kinds of odd, and it makes the resulting .config
files illogical.

Maybe I'm the only one who looks at those things. I do it because I
think they are sometimes easier to just edit directly, but also
because for me it's a quick way to see if somebody has sneaked in new
config options that are on by default when they shouldn't be.

I'd really prefer to not have the resulting config files polluted with
nonsensical config options.

I suspect it would be as simple as adding a

        depends on ICE != n

to that thing, but I didn't get around to testing that. I thought it
would be better to notify the guilty parties.

Anyway, this has obviously not held up me pulling the networking
changes, and you should just see this as (yet another) sign of "yeah,
Linus cares about those config files to a somewhat unhealthy degree".
