Subject: CPUFREQ: Remove cpufreq_stats sysfs entries on module unload.
From: Dave Jones <[email protected]>
commit 13f067537f34456443f61c950cd6dc37d1d5f3ee upstream.
cpufreq_stats leaves behind its sysfs entries, which causes a panic
when something stumbled across them.
(Discovered by unloading cpufreq_stats while powertop was loaded).
