From: Rafael J. Wysocki Date: Sun, 7 Feb 2016 15:05:07 +0000 (+0100) Subject: cpufreq: governor: Rename some data types and variables X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=7bdad34d0890b69c30e8c6a50c9c2311a839fd68;p=openwrt%2Fstaging%2Fblogic.git cpufreq: governor: Rename some data types and variables The ondemand and conservative governors are represented by struct common_dbs_data whose name doesn't reflect the purpose it is used for, so rename it to struct dbs_governor and rename variables of that type accordingly. No functional changes. Signed-off-by: Rafael J.
