Subject[PATCH V2 3/7] thermal/drivers/cpu_cooling: Remove pointless field
Date
The structure cpufreq_cooling_device provides a backpointer to the thermal
device but this one is used for a trace and to unregister. For the trace,
we don't really need this field and the unregister function as the same
pointer passed as parameter. Remove it.
