Subject: [PATCH V2 0/3] Misc changes for siw
Date: Mon, 21 Aug 2023 16:47:40 +0800 [thread overview]
Message-ID: <20230821084743.6489-1-guoqing.jiang@linux.dev> (raw)
V2 changes:
1. add Fixes lines for the first two patches per Leon
Hi,
The first one fix below calltrace which could happen if siw_connect
goto error (I manually set rv to -1 after siw_send_mpareqrep to trigger
it) after cep is allocated.
