Sometimes device recovery fail with this operation. Run test command for many times: echo assert > /sys/kernel/debug/ath12k/wcn7850\ hw2.0_0000\:03\:00.0/simulate_fw_crash While recovery start, ath12k_core_post_reconfigure_recovery() will call ieee80211_restart_hw(), and the restart_work which queued by ieee80211_restart_hw() is running in another thread, it will call into ath12k_mac_op_start() and ath12k_mac_wait_reconfigure(), and the variables ab->recovery_start_count and ab->recovery_start is used in ath12k_mac_wait_reconfigure(), so ath12k need to initialize the variables before queue the restart_work, otherwise ath12k_mac_wait_reconfigure() maybe use the un-initialized variables. Change to initialize the 2 variables earlier and then recovery process become correct.
