The GPIO_LINE_DIRECTION_* definitions have just recently been exposed to
gpio consumers.h by breaking them out in a separate defs.h file.
Use this to validate the gpio direction instead of the hard-coded literal.

Hello,
I suppose you are suggesting a subject change, in that case I will send v2.
Also I can see that automated code review notes that this will not build
on greg's tty tree as 7.0 is not yet merged into it. I will wait for
that to happen
before mailing v2.
BR,
Nikola
