I was going to ask what the next steps were for this series.
Presumably I could post the patch to Russell's patch tracker if folks
want me to do that.  Alternatively it could go through the ARM-SOC
tree?

Thanks for catching!


I'm happy to post up a v6 with these things fixed or I'm happy for
whoever is applying it to make these small fixes themselves.  Any
volunteers?  Olof, Arnd, or Russell: any of you want these patches?
