[ Upstream commitd1378d1d7e] In cpufreq_policy_put_kobj(), policy->rwsem is used. But in cpufreq_policy_alloc(), if freq_qos_add_notifier() returns an error, error path via err_kobj_remove or err_min_qos_notifier will be reached and cpufreq_policy_put_kobj() will be called before policy->rwsem is initialized. Thus, the calling of init_rwsem() should be moved to where before these two error paths can be reached.
