Right, looking at your posted patch [1] we're changing this logic so that normal regulators defined with min == max will be allowed to set_voltage(). Thinking about it that makes sense and cleans the logic up, so I'm in favor of this. I know it's published, but fwiw you have my Acked-by on the posted patch.
