From e9751894000af398d5895b3ee96052f57b80cc44 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 7 Feb 2016 16:23:49 +0100 Subject: [PATCH] cpufreq: governor: Simplify cpufreq_governor_limits() Use the observation that cpufreq_governor_limits() doesn't have to get to the policy object it wants to manipulate by walking the reference chain cdbs->policy_dbs->policy, as the final pointer is actually equal to its argument, and make it access the policy object directy via its argument.
