PARIDE can be built with or without PARPORT support. However, if PARPORT
is configured but not present in the kernel, PARIDE must also be built
as a loadable module.

The curious code above defines a bogus config option which is used only
in the very next line (which you omitted) as an input to dep_tristate
So that the user gets the correct options for building PARIDE.

Perhaps there is a better idiom for doing this, but I don't know what it
is. It's not at all clear to me what the valid expression syntax is for
the 'dependency' arguments to dep_tristate.
