From: Jianglei Nie <niejianglei2021@163.com> stable inclusion from stable-v5.10.148 commit 73e1b27b58a6f5aa5a4955795a57d1613e58a61d category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0WL Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 65e5d27df61283e5390f04b09dc79cd832f95607 ] 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.
