If anyone has any objections, please let me know. ------------------ From: Ivan Abramov [ Upstream commit e69ed6fc9fb3b386b5fcdb9f51623f122cee2ebd ] There's no need to call WARN_ON() in cfg802154_pernet_exit(), since every point of failure in cfg802154_switch_netns() is covered with WARN_ON(), so remove it. Found by Linux Verification Center (linuxtesting.org) with Syzkaller.
