From df57acc415b16299ddef108551c80929a41d5754 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Wed, 29 Jan 2020 18:59:05 -0700 Subject: ath11k: Silence clang -Wsometimes-uninitialized in ath11k_update_per_peer_stats_from_txcompl Clang warns a few times (trimmed for brevity): ../drivers/net/wireless/ath/ath11k/debugfs_sta.c:185:7: warning: variable 'rate_idx' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] It is not wrong, rate_idx is only initialized in the first if block. However, this is not necessarily an issue in practice because rate_idx will only be used when initialized because ath11k_accumulate_per_peer_tx_stats only uses rate_idx when flags is not set to RATE_INFO_FLAGS_HE_MCS, RATE_INFO_FLAGS_VHT_MCS, or RATE_INFO_FLAGS_MCS. Still, it is not good to stick uninitialized values into another function so initialize it to zero to prevent any issues down the line.
