The documentation was wrong, gpiod_get_direction() returns 0/1 instead
of the GPIOF_* flags. The docs were fixed with commit 94fc73094abe47
("gpio: correct docs about return value of gpiod_get_direction"). Now,
fix this user (until a better, system-wide solution is in place).

Thanks for the Reviewed-by Simon.  I have applied it to the original mail.

Do you know why you mail wasn't sent attached to the original thread?
For some reason I received this mail on it's own i.e. not in reply
to the original.

Changes since V1:
	* rebased to top-of-linus-tree
	* added tag from Daniel, thanks!

Through which tree does this need to go?
