From bd1d129daa3ede265a880e2c6a7f91eab0f4dc62 Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Fri, 20 May 2022 12:43:16 -0700 Subject: [PATCH] wifi: ath6k: silence false positive -Wno-dangling-pointer warning on GCC 12 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit For some reason GCC 12 decided to complain about the common pattern of queuing an object onto a list on the stack in ath6k: inlined from ‘ath6kl_htc_mbox_tx’ at drivers/net/wireless/ath/ath6kl/htc_mbox.c:1142:3: include/linux/list.h:74:19: warning: storing the address of local variable ‘queue’ in ‘*&packet_15(D)->list.prev’ [-Wdangling-pointer=] 74 | new->prev = prev; | ~~~~~~~~~~^~~~~~ Move the warning to W=1, hopefully it goes away with a compiler update.
