CPUFreq core does following at multiple places:
module_{get|put}(cpufreq_driver->owner)).
This is done to make sure module doesn't get unloaded if it is currently in use.
This will work only if the .owner field of cpufreq driver is initialized with a
valid pointer.
This field wasn't initialized for this driver, lets initialize it with
THIS_MODULE.
