As this is selected by the driver it shouldn't have any help text -
there's no point in users seeing the option since it's useless by
itself.  If we get enough to make an option useful either a menu or
dependencies from the individual MFDs would be a better option.

This looks suspicious.

Typically subsys_initcall() has been used.
