You mean the #ifdef? It wasn't there, but Olof figured out that it
breaks !CONFIG_OF builds:

http://article.gmane.org/gmane.linux.ports.tegra/18473

as of_allnodes is only defined when CONFIG_OF. I had a choice of
#ifdefing the assignment above or providing a dummy symbol. The latter
doesn't seem sensibly, as there should be no other users for it (the
symbol).
