From 8edb0a6e48d147bb2aa466c58e03c52d2b0d6ee7 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Wed, 11 May 2016 19:10:42 +0200 Subject: [PATCH] intel_pstate: Use sample.core_avg_perf in get_avg_pstate() Notice that get_avg_pstate() can use sample.core_avg_perf instead of carrying the same division again, so make it do that.
