There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). The usage pattern of the completion is: waiter context waker context scan.started ------------ ath10k_start_scan() lockdep_assert_held(conf_mutex) auth10k_wmi_start_scan() wait_for_completion_timeout(scan.started) ath10k_wmi_event_scan_start_failed() complete(scan.started) ath10k_wmi_event_scan_started() complete(scan.started) scan.completed -------------- ath10k_scan_stop() lockdep_assert_held(conf_mutex) ath10k_wmi_stop_scan() wait_for_completion_timeout(scan.completed) __ath10k_scan_finish() complete(scan.completed) scan.on_channel --------------- ath10k_remain_on_channel() mutex_lock(conf_mutex) ath10k_start_scan() wait_for_completion_timeout(scan.on_channel) ath10k_wmi_event_scan_foreign_chan() complete(scan.on_channel) offchan_tx_completed -------------------- ath10k_offchan_tx_work() mutex_lock(conf_mutex) reinit_completion(offchan_tx_completed) wait_for_completion_timeout(offchan_tx_completed) ath10k_report_offchain_tx() complete(offchan_tx_completed) install_key_done ---------------- ath10k_install_key() lockep_assert_held(conf_mutex) reinit_completion(install_key_done) wait_for_completion_timeout(install_key_done) ath10k_htt_t2h_msg_handler() complete(install_key_done) vdev_setup_done --------------- ath10k_monitor_vdev_start() lockdep_assert_held(conf_mutex) reinit_completion(vdev_setup_done) ath10k_vdev_setup_sync() wait_for_completion_timeout(vdev_setup_done) ath10k_wmi_event_vdev_start_resp() complete(vdev_setup_done) ath10k_monitor_vdev_stop() lockdep_assert_held(conf_mutex) reinit_completion(vdev_setup_done() ath10k_vdev_setup_sync() wait_for_completion_timeout(vdev_setup_done) ath10k_wmi_event_vdev_stopped() complete(vdev_setup_done) thermal.wmi_sync ---------------- ath10k_thermal_show_temp() mutex_lock(conf_mutex) reinit_completion(thermal.wmi_sync) wait_for_completion_timeout(thermal.wmi_sync) ath10k_thermal_event_temperature() complete(thermal.wmi_sync) bss_survey_done --------------- ath10k_mac_update_bss_chan_survey lockdep_assert_held(conf_mutex) reinit_completion(bss_survey_done) wait_for_completion_timeout(bss_survey_done) ath10k_wmi_event_pdev_bss_chan_info() complete(bss_survey_done) All complete() calls happen while the conf_mutex is taken. That means at max one waiter is possible. Signed-off-by:
