[PATCH 2/3] intel_pstate: Use sample.core_avg_perf in get_avg_pstate()
From: Rafael J. Wysocki
Date: Fri May 06 2016 - 19:45:41 EST
From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>
Notice that get_avg_pstate() can use sample.core_avg_perf instead of
carrying the same division again, so make it do that.
