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.

Are you planning on sending a non-RFC version of this?
If so is it an urgent fix I should send upstream now? And if so should it
also be CC'ed to stable?
cheers
