All the callers of of_cpufreq_power_cooling_register() have almost identical code and it makes more sense to move that code into the helper as its all about reading DT properties. This got rid of lot of redundant code. Acked-by: Eduardo Valentin <edubezval@gmail.com> Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
