In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to add this dependency and ifdef
sections of code using inb()/outb() as alternative access methods.

Your oneline-summary doesn't cover this file.

Thanks, I guess then I should go with "char: depend on HAS_IOPORT"

Why? drivers/char/lp.c doesn't use I/O accessors, and should work with
all parport drivers.

You're right that should work.
