From: Eduardo Valentin Date: Mon, 12 Nov 2012 15:58:50 +0000 (+0000) Subject: thermal: cpu cooling: use const parameter while registering X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=3778ff5c709899a29cefe4b3077a926d0e1e9785;p=deliverable%2Flinux.git thermal: cpu cooling: use const parameter while registering There are predefined cpu_masks that are const data structures. This patch changes the cpu cooling register function so that those const cpu_masks can be used, without compilation warnings. include/linux/cpumask.h * The following particular system cpumasks and operations manage * possible, present, active and online cpus. * * cpu_possible_mask- has bit 'cpu' set iff cpu is populatable * cpu_present_mask - has bit 'cpu' set iff cpu is populated * cpu_online_mask - has bit 'cpu' set iff cpu available to scheduler * cpu_active_mask - has bit 'cpu' set iff cpu available to migration * Signed-off-by: Eduardo Valentin Signed-off-by: Zhang Rui --- diff --git a/drivers/thermal/cpu_cooling.c b/drivers/thermal/cpu_cooling.c index 6f94c2cac1f0..836828e29a87 100644 --- a/drivers/thermal/cpu_cooling.c +++ b/drivers/thermal/cpu_cooling.c @@ -313,7 +313,7 @@ static struct notifier_block thermal_cpufreq_notifier_block = { * @clip_cpus: cpumask of cpus where the frequency constraints will happen. */ struct thermal_cooling_device *cpufreq_cooling_register( - struct cpumask *clip_cpus) + const struct cpumask *clip_cpus) { struct thermal_cooling_device *cool_dev; struct cpufreq_cooling_device *cpufreq_dev = NULL; diff --git a/include/linux/cpu_cooling.h b/include/linux/cpu_cooling.h index 851530128e65..b30cc79c7a82 100644 --- a/include/linux/cpu_cooling.h +++ b/include/linux/cpu_cooling.h @@ -35,7 +35,7 @@ * @clip_cpus: cpumask of cpus where the frequency constraints will happen */ struct thermal_cooling_device *cpufreq_cooling_register( - struct cpumask *clip_cpus); + const struct cpumask *clip_cpus); /** * cpufreq_cooling_unregister - function to remove cpufreq cooling device. @@ -44,7 +44,7 @@ struct thermal_cooling_device *cpufreq_cooling_register( void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev); #else /* !CONFIG_CPU_THERMAL */ static inline struct thermal_cooling_device *cpufreq_cooling_register( - struct cpumask *clip_cpus) + const struct cpumask *clip_cpus) { return NULL; }
