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 many cpufreq driver, lets initialize it with THIS_MODULE.
Isn't it possible to do this inside cpufreq_register_driver function in a similar way as done for platform_driver_register [1].
Don't know if its possible to set it to something other than THIS_MODULE. In which case we want something else to be done.
