[PATCH 3/4] wifi: ath11k: avoid forward declaration of ath11k_mac_start_vdev_delay()
Baochen Qiang

Mon Jan 22 18:56:59 PST 2024
Currently ath11k_mac_start_vdev_delay() needs a forward declaration because
it is defined after where it is called. Avoid this by re-arranging
ath11k_mac_station_add() and ath11k_mac_op_sta_state().
No functional changes. Compile tested only.
