I think it should be not done like this. (Yes, I know why you did that)
Perhaps Linus will accept a patch to move direction flags to some header
feasible via consumer.h.
Linus?
Or if we wish to hide:
static inline bool gpiod_is_direction_out() {}
static inline bool gpiod_is_direction_in() {}

P.S. Yep, I saw some other upstreamed patch doing this kind of
comparison.
