Date: Tue, 13 Sep 2022 14:39:41 +0800 From: Jianglei Nie <niejianglei2021@....com> To: irusskikh@...vell.com, davem@...emloft.net, edumazet@...gle.com, kuba@...nel.org, pabeni@...hat.com Cc: netdev@...r.kernel.org, linux-kernel@...r.kernel.org, Jianglei Nie <niejianglei2021@....com> Subject: [PATCH] net: atlantic: fix potential memory leak in aq_ndev_close() If aq_nic_stop() fails, aq_ndev_close() returns err without calling aq_nic_deinit() to release the relevant memory and resource, which will lead to a memory leak. We can fix it by deleting the if condition judgment and goto statement to call aq_nic_deinit() directly after aq_nic_stop() to fix the memory leak.
