Message-Id: <1360170133-5066-5-git-send-email-dirk.brandewie@gmail.com> Date: Wed, 6 Feb 2013 09:02:11 -0800 From: dirk.brandewie@...il.com To: linux-kernel@...r.kernel.org, cpufreq@...r.kernel.org Cc: Dirk Brandewie <dirk.brandewie@...il.com> Subject: [PATCH 3/5] cpufreq: Do not track governor name for scaling drivers with internal governors. From: Dirk Brandewie <dirk.brandewie@...il.com> 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 <dirk.j.brandewie@...el.com> Acked-by: Viresh Kumar <viresh.kumar@...aro.org> --- drivers/cpufreq/cpufreq.c | 4 +++- 1 files changed, 3 insertions(+), 1 deletions(-) diff --git a/drivers/cpufreq/cpufreq.c b/drivers/cpufreq/cpufreq.c index 0ba0344..e772053 100644 --- a/drivers/cpufreq/cpufreq.c +++ b/drivers/cpufreq/cpufreq.c @@ -1049,7 +1049,9 @@ static int __cpufreq_remove_dev(struct device *dev, struct subsys_interface *sif __cpufreq_governor(data, CPUFREQ_GOV_STOP); #ifdef CONFIG_HOTPLUG_CPU - strncpy(per_cpu(cpufreq_cpu_governor, cpu), data->governor->name, + if (!cpufreq_driver->setpolicy) + strncpy(per_cpu(cpufreq_cpu_governor, cpu), + data->governor->name, CPUFREQ_NAME_LEN); #endif -- 1.7.7.6 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
