I suspect that this is the result of an error on my part when I rebased
the code on top of v3.16-rc1 before making it available to next.

The missing code appears to lie in "ARM: shmobile: rcar-gen2: Update for
of_get_flat_dt_prop() update".


Olof, I'd prefer not to rebase my branches in next. But if you'd like
me to do so to clean up this problem then let me know.
