[82/89] CPUFREQ: Remove cpufreq_stats sysfs entries on module unload.

From: Greg KH
Date: Thu Jun 16 2011 - 03:03:00 EST

2.6.39-stable review patch. If anyone has any objections, please let us know.


From: Dave Jones <davej@xxxxxxxxxx>

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).
