Viresh Kumar 6dc8c51a76 cpufreq: sched: Fix kernel crash on accessing sysfs file ... If the cpufreq driver hasn't set the CPUFREQ_HAVE_GOVERNOR_PER_POLICY flag, then the kernel will crash on accessing sysfs files for the sched governor. CPUFreq governors we can have the governor specific sysfs files in two places: A. /sys/devices/system/cpu/cpuX/cpufreq/<governor> B. /sys/devices/system/cpu/cpufreq/<governor> The case A. is for governor per policy case, where we can control the governor tunables for each policy separately. The case B. is for system wide tunable values. The schedfreq governor only implements the case A. and not B. The sysfs files in case B will still be present in /sys/devices/system/cpu/cpufreq/<governor>, but accessing them will crash kernel as the governor doesn't support that. Moreover the sched governor is pretty new and will be used only for the ARM platforms and there is no need to support the case B at all. Hence use policy->kobj instead of get_governor_parent_kobj(), so that we always create the sysfs files in path A. Signed-off-by: Viresh Kumar <viresh.kumar@linaro.org>		2016-11-16 09:46:21 -08:00
