From fa69e33f7d38e658583ff910642da7ea4515ad74 Mon Sep 17 00:00:00 2001 From: Dirk Brandewie Date: Wed, 6 Feb 2013 09:02:11 -0800 Subject: cpufreq: Do not track governor name for scaling drivers with internal governors. Scaling drivers that implement internal governors do not have governor structures assocaited with them. Only track the name of the governor associated with the CPU if the driver does not implement cpufreq_driver.setpolicy() Signed-off-by: Dirk Brandewie Acked-by: Viresh Kumar Signed-off-by: Rafael J.
