The last patch in this series makes the flags parameter for the various
gpiod_get* functions mandatory and so allows to remove an ugly cpp hack
introduced in commit 39b2bbe3d7 (gpio: add flags argument to gpiod_get*()
functions) for v3.17-rc1.
The other nine commits fix the last remaining users of these functions that
don't pass flags yet. (Only etraxfs-uart wasn't fixed; this driver's use of the
gpiod functions needs fixing anyhow.)
