From f8510d67d658c4f4fb7dcb13560d4c99e4de5082 Mon Sep 17 00:00:00 2001 From: Nathan Chancellor Date: Thu, 7 Mar 2019 17:03:22 -0700 Subject: [PATCH] iwlwifi: mvm: Change an 'else if' into an 'else' in iwl_mvm_send_add_bcast_sta When building with -Wsometimes-uninitialized, Clang warns: drivers/net/wireless/intel/iwlwifi/mvm/sta.c:2114:12: warning: variable 'queue' is used uninitialized whenever 'if' condition is false [-Wsometimes-uninitialized] Clang can't evaluate at this point that WARN(1, ...) always returns true because __ret_warn_on is defined as !!(condition), which isn't immediately evaluated as 1. Change this branch to else so that it's clear to Clang that we intend to bail out here.
