Maybe don't mention keyboards just yet on the line above since the
driver is now supposed to support other devices too.

I'd name this just lenovo_input_mapping() for now.

And add this separation in a preparatory patch, more or less equal to
your previous patch 1, which would become a following patch on top of
the rename one.

break after return is not needed.
I also like explicit default cases, but I guess it's just personal
preference.

I have no definitive opinion on these renames, I guess they are OK;
maybe having these functions end in _store and _show is slightly more
readable, but this is not a big deal.

Just curios, why did the function change the signature too here?
The "id" argument is not used in either of the "internal" probe
routines.
