In 'ath11k_dp_rx_mon_dest_process()', 'mon_dst_srng' points to a member of 'srng_list', which is a fixed-size array inside 'struct ath11k_hal'. This way, if 'ring_id' is valid (i. e. between 0 and HAL_SRNG_RING_ID_MAX - 1 inclusive), 'mon_dst_srng' can't be NULL and so relevant check may be dropped.
