Kant Fan 8e354518f5 thermal: devfreq_cooling: use local ops instead of global ops ... commit b947769b8f upstream. Fix access illegal address problem in following condition: There are multiple devfreq cooling devices in system, some of them has EM model but others do not. Energy model ops such as state2power will append to global devfreq_cooling_ops when the cooling device with EM model is registered. It makes the cooling device without EM model also use devfreq_cooling_ops after appending when registered later by of_devfreq_cooling_register_power() or of_devfreq_cooling_register(). The IPA governor regards the cooling devices without EM model as a power actor, because they also have energy model ops, and will access illegal address at dfc->em_pd when execute cdev->ops->get_requested_power, cdev->ops->state2power or cdev->ops->power2state.
