Series [v1,01/10] cpufreq: Add thermal_cooling_device pointer to struct cpufreq_policy | expand

Commit Message

Amit Kucheria Jan. 14, 2019, 4:35 p.m. UTC 
Use the CPUFREQ_AUTO_REGISTER_COOLING_DEV flag to allow cpufreq core to
automatically register as a thermal cooling device.

This allows removal of boiler plate code from the driver.
