Before querying a GPIO to determine its direction, the GPIO should be
formally requested.  This allows the GPIO driver to block access to
unavailable GPIOs, which makes it easier for some drivers to support
sparse GPIO maps.

Have you push it to git.kernel.org?  I don't see it.

It's right there on the "devel" branch from the GPIO git tree.
