Subject[PATCH v1 01/10] cpufreq: Add thermal_cooling_device pointer to struct cpufreq_policy
Date
Several cpufreq drivers register themselves as thermal cooling devices.
Adding a pointer to struct cpufreq_policy removes the need for them to
store this pointer in a private data structure.

We can then auto-register the cpufreq driver as a thermal cooling device
from cpufreq core code.
