None of the cpufreq governors currently in the tree will ever fail an invocation of the ->governor() callback with the event argument equal to CPUFREQ_GOV_POLICY_EXIT (unless invoked with incorrect arguments which doesn't matter anyway) and it wouldn't really make sense to fail it, because the caller won't be able to handle that failure in a meaningful way. Accordingly, rearrange the code in the core to make it clear that this call never fails. Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com> Acked-by: Viresh Kumar <viresh.kumar@linaro.org>
