Yep. I think I might pull this change out of the RFC and send it
separately. I can also do some conversions for existing drivers - but I
won't probably be able to do all of the drivers. I see no way of doing
any search and replace scripting here - this conversion is going to be
manual work :/

Right. Besides the 0Day test suite did already spot a few redefinition
problems when some drivers do define GPIO_IN and/or GPIO_OUT... So I'll
change the defines to what you suggest here.
