Please make sure you take care of these issues:
- suspend/resume
- hotplug
- module insert/remove

Ok, I was just at the current code. Does cpufreq_unregister_driver() even
really work correctly as it stands?

It doesn't even seem to stop any of the governors/policies before it just
set the cpufreq_driver pointer to NULL.

So, technically my v2 patch doesn't even make anything worse when it comes
to unregistering the cpufreq driver.

Are you really sure about this? I have tested this *myself* earlier..

subsys_interface_unregister() should take care of stopping/freeing governor
stuff..
