From 702c9e542a25cf95683c08c56e711eddb80020ac Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 18 Feb 2016 02:21:21 +0100 Subject: cpufreq: governor: Add a ->start callback for governors To avoid having to check the governor type explicitly in the common code in order to initialize data structures specific to the governor type properly, add a ->start callback to struct dbs_governor and use it to initialize those data structures for the ondemand and conservative governors.
