From ac13a7842ab46a87aa315514d6d7e19b03cb2adc Mon Sep 17 00:00:00 2001 From: Dmitry Antipov Date: Wed, 6 Sep 2023 12:36:55 +0300 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.
