From: zhuguangqing <[email protected]>
1. devfreq_cooling.c: The variable *tz is not used in
devfreq_cooling_get_requested_power(), devfreq_cooling_state2power()
and devfreq_cooling_power2state().
2. cpufreq_cooling.c: After 84fe2cab48590, the variable *tz is not used
anymore in cpufreq_get_requested_power(), cpufreq_state2power() and
cpufreq_power2state().
Remove the variable *tz.
