Subject[PATCH] [54/99] CPUFREQ: Remove cpufreq_stats sysfs entries on module unload.
Date
2.6.35-longterm review patch.  If anyone has any objections, please let me know.

------------------
From: Dave Jones <davej@redhat.com>

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).
