+Subject: [PATCH] wifi: ath11k: drop NULL pointer check in
+ ath11k_update_per_peer_tx_stats()
+
+Since 'user_stats' is a fixed-size array of 'struct htt_ppdu_user_stats'
+in 'struct htt_ppdu_stats', any of its member can't be NULL and so
+relevant check may be dropped.
+
+Found by Linux Verification Center (linuxtesting.org) with SVACE.
