I'll only get called at the same time as it is called today. 
__cpufreq_remove_dev_prepare is now renamed to __cpufreq_remove_dev. And 
this function is called from there.

The only time stop does get called is when __cpufreq_remove_dev is 
called on the last CPU of a policy. So, functionally it's identical.

Btw, I already added logs to all cpufreq driver ops and checked the 
calls come in the same order with and without my changes.
