X-Git-Tag: v3.12-rc1~45^2~12^3 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=044d5c26da262fa433dacbe1c6962459050d6b06;p=pandora-kernel.git Thermal/cpu_cooling: Return directly for the cpu out of allowed_cpus in the cpufreq_thermal_notifier() cpufreq_thermal_notifier() is to change the cpu's cpufreq in the allowed_cpus mask when associated thermal-cpufreq cdev's cooling state is changed. It's a cpufreq policy notifier handler and it will be triggered even if those cpus out of allowed_cpus has changed freq policy. cpufreq_thermal_notifier() checks the policy->cpu. If it belongs to allowed_cpus, change max_freq(default to 0) to the desire cpufreq value and pass 0 and max_freq to cpufreq_verify_within_limits() as cpufreq scope. But if not, do nothing and max_freq will remain 0. This will cause the cpufreq scope to become 0~0. This is not right. This patch is to return directly after finding cpu not belonging to allowed_cpus. Signed-off-by: Lan Tianyu Signed-off-by: Zhang Rui --- Reading git-diff-tree failed
