The call trace is like:\n\nath11k_bcn_tx_status_event()\n-> rcu_read_lock()\n-> ath11k_mac_bcn_tx_event()\n\t-> ath11k_mac_setup_bcn_tmpl()\n\t……\n\t\t-> ath11k_wmi_bcn_tmpl()\n\t\t\t-> ath11k_wmi_cmd_send()\n-> rcu_read_unlock()\n\nCommit 886433a98425 (\"ath11k: add support for BSS color change\") added the\nath11k_mac_bcn_tx_event(), commit 01e782c89108 (\"ath11k: fix warning\nof RCU usage for ath11k_mac_get_arvif_by_vdev_id()\") added the RCU lock\nto avoid warning but also introduced this BUG.\n\nUse work queue to avoid directly calling ath11k_mac_bcn_tx_event()\nduring RCU critical sections. No need to worry about the deletion of vif\nbecause cancel_work_sync() will drop the work if it doesn't start or\nblock vif deletion until the running work is done.\n\nTested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-03125-QCAHSPSWPL_V1_V2_SILICONZ_LITE-3.6510.30"
