This battery appears only to be used by a single board (DA850), so it
makes sense to add this to the Kconfig file so that users don't build
the module unnecessarily. It currently seems to be built for the x86
Arch Linux kernel where it's probably not doing much good.

It would probably also make sense to add "default n" since it only
applies to one board in the entire arch.
BATTERY_LEGO_EV3 is already explicitly set to "m" in the appropriate
defconfig file, so I don't think it would break anything.

Ah ok. That makes sense. Would you like me to send a follow-on patch for
this?

You can just send a v2 patch that includes the change below and the
additional change.

I've just had a look at the documentation[1] and it seems that as there's
no "default y" there it'll default to n anyway. Have I got that right?

Yes, that seems right. That makes me wonder why this would have been enabled in
the Arch Linux kernel for x86 then.

Not sure, maybe the Arch devs like Lego? ;-)
Are you happy to give an Acked-by for this anyhoo?
@Sebastian, are you happy to pick up this patch?
Best,
Alex
