cpufreq: schedutil: Pass sg_policy to get_next_freq()
get_next_freq() uses sg_cpu only to get sg_policy, which the callers of get_next_freq() already have. Pass sg_policy instead of sg_cpu to get_next_freq(), to make it more efficient. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
