True, but that's the issue that we have of_specific API. If someone propose
the common API for the agnostic approach,  it would be nice, but I am not
the one. And TBH I do not see the advantage of it right now as almost every
GPIO driver is using its own labeling schema (*). Note, that this patch also
fixes a memory leak as a side effect.

*) the legacy API is mostly used by PPC code, do you want that of_mm_* thingy
to be moved to PPC specific code instead of killing it? Would be done this
way as well.

Crap, I most likely built something else and not these files...
I have carefully build-test this for v2.

Note to myself: Never ever send the patches on Friday evenings! :-)
