Ah, could you be more specific about the race you're talking of ?

My understanding was that cpufreq-dt-platdev does create the device, and
cpufreq-dt is a driver for it, so there is no race but a direct relationship
AFAIU.

Ok, as you wish, let it become number 3 and (2, 3) become (1, 2).

Cheers.
