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.
