In a future patch HAS_IOPORT=n will result in inb()/outb() and friends
not being declared. We thus need to depend on HAS_IOPORT even when
compile testing only.

This breaks code selecting ISAPNP and not depending on it. See
https://lore.kernel.org/linux-acpi/202303211932.5gtCVHCz-lkp@xxxxxxxxx/T/#u
for example.
I'm dropping the patch now, please fix and resend.
Sorry if this wasn't super clear but all patches in this series depend
on patch 1 which introduces the HAS_IOPORT Kconfig option. There's
really two options, either the whole series goes via e.g. Arnd's tree
at once or we first only merge patch 1 and then add the rest per
subsystem until finally the last patch can remove inb()/outb() when
HAS_IOPORT is unset.
Well, it looks like you need to decide on the approach then and tell
people what it is.
If I see an individual patch without context, this is quite hard to
figure out.
That said I'm a little unsure about the linked error if that is just
due to missing HAS_IOPORT or something else. I'll still have to try
with the instructions in that mail and will report back if it is
something else.
Thanks,
Niklas
