I think you uncovered a bug. This is however not the best fix IMO.

Sorry for not understanding the issue at first, I am sometimes
pretty slow in the head. :(

I'm sending a patch that I hope fixes the real problem in an
elegant way, and makes it possible to just define dirin and
BGPIOF_READ_OUTPUT_REG_SET.

Yours,
