From: Dongliang Mu <mudongliangabcd@gmail.com> stable inclusion from stable-v5.10.84 commit e26dab79e16b73efe878335d8cbab8a03f4995f4 bugzilla: 186030 https://gitee.com/openeuler/kernel/issues/I4QV2F Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- commit f4a8adbfe4841491b60c14fe610571e1422359f9 upstream. The commit c55211892f46 ("dpaa2-eth: support PTP Sync packet one-step timestamping") forgets to destroy workqueue at the end of remove function. Fix this by adding destroy_workqueue before fsl_mc_portal_free and free_netdev.
