When enable debug config, it print below warning while shut down wlan interface shuh as run "ifconfig wlan0 down". The reason is because ar->regd_update_work is ran once, and it is will call wiphy_lock(ar->hw->wiphy) in function ath11k_regd_update() which is running in workqueue of ieee80211_local queued by ieee80211_queue_work(). Another thread from "ifconfig wlan0 down" will also accuqire the lock by wiphy_lock(sdata->local->hw.wiphy) in function ieee80211_stop(), and then it call ieee80211_stop_device() to flush_workqueue(local->workqueue), this will wait the workqueue of ieee80211_local finished. Then deadlock will happen easily if the two thread run meanwhile. Below warning disappeared after this change.
