I think that you need to teach the driver to dynamically look
for a genio driver so you don't get compilation errors,
then it will find any genio driver or the dummy driver if that
is compiled in.

At the least you need a Kconfig and Makefile entry for the
dummy_genio driver...

Yours,
Linus Walleij
