X-Git-Tag: firefly_0821_release~10164^2~6^2~19 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=21dfd57873ccc7e4ff42d3dbc281cafe03dfb4a4;p=firefly-linux-kernel-4.4.55.git CPUFREQ: Remove cpufreq_stats sysfs entries on module unload. 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).
