[PATCH V2 03/17] thermal: cpu_cooling: Name cpufreq cooling devices as cpufreq_cdev

From: Viresh Kumar
Date: Mon Apr 17 2017 - 02:06:29 EST

Objects of "struct cpufreq_cooling_device" are named a bit
inconsistently. Lets use cpufreq_cdev everywhere. Also note that the
lists containing such devices is renamed similarly too.
