Yes, exactly like this. :)

Patcha applied for kernel v4.4.

I have five other drivers using port-based I/O:

gpio-f7188x.c
gpio-it87.c
gpio-sch.c
gpio-sch311x.c
gpio-ts5500.c

Do you think it makes sense to move all of these in under
the "ISA GPIO drivers" menu as well? I guess they all require
ISA after all.

(Added their maintainers to the To: line so I can get some input
on this.)
