Generally speaking, no.

There may be places that I have used it improperly, but I think it is
generally okay to use.

If you are refering to the discussion with Frank and Stephen in RFC
v4, my take was that the resolution was that there were some things I
needed to fix in its implementation, but it is conceptually okay, and
that Frank doesn't want me to use it in drivers/of/unittest.c.
Consequently, I fixed the implementation issues that Frank and Stephen
pointed out, and I am holding off on drivers/of/unittest.c for this
patchset. The usage in this file should be fine.
