Thanks for the review, Jonathan.  I agree with your remark regarding the
potentially confusing name of the variable holding the S64x0 keymap.

As in the past, we have at least two options: I can either post v2 of
all eight patches with three characters changed or you can provide your
Reviewed-by for v1, in which case I will kindly ask the maintainers to
run:

    sed -i 's|s6400|s64x0|;' drivers/platform/x86/fujitsu-laptop.c

after applying patch 7/8.  Given that this series does a bit more than
the cleanup series I posted previously, I sense it might be a good idea
to defer submitting v2 until after subsystem maintainers review v1, just
in case they find more issues.  If that happens, I will post v2 to avoid
confusion.  If not, then v1 can be applied with the one-liner above
taken into account (or I can post v2 anyway if that would be preferred
by Darren and Andy).

In other words, I am happy to follow whatever route you and the
subsystem maintainers suggest and I just want to avoid spamming the
mailing list.
