I don't know if we're talking about the same thing here.
My point was that passing a domain-mapped IRQ number into mfd_add_devices
with another domain will result in the attempt to map that number into
another domain, which does not work.

The debug driver should not need to worry about domains, as long
as the ab8500->domain passed into mfd_add_devices is correctly
set up.
