KASAN enabled:

drivers/net/wireless/ath/ath11k/qmi.c:3199:13: warning: stack frame size (1560) exceeds limit (1024) in 'ath11k_qmi_driver_event_work' [-Wframe-larger-than]
drivers/net/wireless/ath/ath11k/dp_rx.c:5244:5: warning: stack frame size (1304) exceeds limit (1024) in 'ath11k_dp_rx_process_mon_status' [-Wframe-larger-than]

      wifi: ath11k: mark some QMI driver event helpers as noinline
      wifi: ath11k: mark ath11k_dp_rx_mon_mpdu_pop() as noinline
      wifi: ath11k: mark ath11k_wow_convert_8023_to_80211() as noinline
