I don't know if my opinion counts for anything here, but I actually read
the patch and it looked harmless.  But that is because it mostly does
nothing other than replace calls to find_path_device() with calls to
of_find_node_by_path() and insserts of_node_put() in reasonable looking
places.  So what can go wrong?

I didn't actually read of_find_node_by_path(), however, since its not
in this patch.
