Series [v2,1/4] devfreq: Register devfreq as a cooling device on demand | expand

Commit Message

Daniel Lezcano March 5, 2021, 5:03 p.m. UTC
The devfreq core code is able to register the devfreq device as a
cooling device if the 'is_cooling_device' flag is set in the profile.

Use this flag and remove the cooling device registering code.

Tested on dragonboard 845c
