Hi Moritz,

I agree with Rob's suggested one line solution (that I initially misunderstood).
The one line fix is to add "if (err)" immediately following label "err_out" in
of_resolve_phandles().

As far as patch 2/2, I'm not bothered by the two instances of line over 80 chars.
But if Rob wants to take patch 2/2 I have no objection.
