Sorry. I'm not sure what you mean by the off-by-one error though. IIRC we initialize the structure using named fields.
What I meant was that remember to also remove the second empty field in ahb2_fixed_predivs. Maxime -- Maxime Ripard, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
