Tero Kristo 2b7e2251c4 cpufreq: intel_pstate: Fix energy_performance_preference for passive ... [ Upstream commit 03f44ffb3d ] If the intel_pstate driver is set to passive mode, then writing the same value to the energy_performance_preference sysfs twice will fail. This is caused by the wrong return value used (index of the matched energy_perf_string), instead of the length of the passed in parameter. Fix by forcing the internal return value to zero when the same preference is passed in by user. This same issue is not present when active mode is used for the driver.
