I think that's a preexisting bug and I have no idea what the
correct solution is. Looking for HD64461 shows it being used
both with inw/outw and readw/writew, so there is no way to have
the correct type. The sh __raw_readw() definition hides this bug,
but that is a problem with arch/sh and it probably hides others
as well.
