Yes. In v6 rtw_core_stop() cancels csa_beacon_work next to update_beacon_work and clears csa_vif, which also covers the firmware recovery, so the wiphy_lock() in rtw_fw_recovery_work() goes away. > > + if (conf->csa_active) > > + rtw_fw_csa_start(rtwdev, vif); > > Is this a necessary case? Can't rtw_ops_channel_switch_beacon() handle it? It is the restart case. After ieee80211_restart_hw(), ieee80211_reconfig() replays BSS_CHANGED_BEACON with csa_active still set, and drv_channel_switch_beacon() is only called from __ieee80211_channel_switch(), so without this the countdown would not resume after a firmware recovery. v6 says so in a comment, and the same path stops the countdown when the beacon comes back without csa_active, which is how mac80211 ends a switch.
