is there a specific reason for keeping this change separate?
While it is nice for documentation reasons, as it stands now the previous 
patch introduces a regression (cpufreq trying to scale without regulators) and 
immediately fixes it here.

So if you're ok with it, I'd like to merge this one back into the previous 
patch when applying.
