Quite often drivers set only "write" permission assuming that this

However IODA2 is strict about this and produces an EEH when "read"
permission is not and reading happens.
This adds a workaround in IODA code to always add the "read" bit when
the "write" bit is set.

Just posted.
If so is it an urgent fix I should send upstream now?
Yes.
> And if so should it also be CC'ed to stable?
Ben suggested that yes, it should. Thanks. Sorry about breaking things.
