This driver was born as a builtin only one, indeed it is bool and not
tristate in Kconfig and is registered through builtin_platform_driver().
Hence I've set it =y in defconfig. A quick check transforming it to be
dynamically loaded as a module confirm that something is not working, and
I agree with you that, in theory, this should also be a loadable module.
I need some investigation on that though...

Many thanks,
Andrea
