[PATCH 0/1] cpufreq: Fix show()/store() issue for hotplugging

['Guanjun']

From: Zelin Deng <zelin.deng@xxxxxxxxxxxxxxxxx>

Hello maintainers,

After I brought one CPU (64) offline, I got failure when I used lscpu:
lscpu: cannot read /sys/devices/system/cpu/cpu64/cpufreq/cpuinfo_max_freq: Device or resource busy

I found in commit d4627a287e251, policy_is_inactive() check was added to
avoid the case in which policy initialization failed. However it didn't
consider the situation in which policy has been created successfully but
is not inactive: CPU is hotplugging offline.

This patch just add an addtional check whether CPU is online or not to
fix the issue.
