From a1a20f3ad1c595217a75d78fec50b886c8474374 Mon Sep 17 00:00:00 2001 From: Dirk Brandewie Date: Wed, 6 Feb 2013 09:02:11 -0800 Subject: [PATCH] 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.
