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.
