commit b14893a62c73af0eca414cfed505b8c09efc613c tries to address a lockdep issue, but it introduces new deadlock when doing governor switching. store(lock_policy_rwsem_write)->store_scaling_governor->__cpufreq_set_policy-> cpufreq_governor_dbs->dbs_timer_exit->cancel_delayed_work_sync(hold fake work lock) but when the dbs work runs: run_workqueue(hold fake work lock)->do_dbs_timer(lock_policy_rwsem_write) I didn't find an easy way to fix this deadlock, hopes your guys have.
