cpufreq: governors: Remove duplicate check of target freq in supported range
Function __cpufreq_driver_target() checks if target_freq is within policy->min and policy->max range. generic_powersave_bias_target() also checks if target_freq is valid via a cpufreq_frequency_table_target() call. So, drop the unnecessary duplicate check in *_check_cpu(). Signed-off-by: Stratos Karafotis <stratosk@semaphore.gr> Acked-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J.
