| Subject: CPUFREQ: Remove cpufreq_stats sysfs entries on module unload. |
| |
| 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). |
