Not necessarily. Also consider the case where cpufreq driver is already working
for a set of CPUs. And a new set of CPUs (that will share the policy) are
getting physically added to the system.

Anyway, even if there is no problem at all, I do agree with Russell that it will
be better to do operations on behalf of the devices only when we are requested
for those devices.
