From 686cc637c99324ad52a6f8e59181f6407405bfe2 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Mon, 8 Feb 2016 23:41:10 +0100 Subject: [PATCH] cpufreq: governor: Rename skip_work to work_count The skip_work field in struct policy_dbs_info technically is a counter, so give it a new name to reflect that. No functional changes. Signed-off-by: Rafael J.
