Subject: [PATCH 00/15] cpufreq: initialize drivers .owner field with THIS_MODULE

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.

Rebased over: v3.11-rc3 and pushed here:
