This series is inspired by similar series in ieee802154. As far as I know,
there were no WARN_ON triggers in this code so far, but since it's almost
identical to cfg802154_* counterparts, same changes are proposed.

Link to ieee802154 series: https://lore.kernel.org/netdev/20250403101935.991385-1-i.abramov@mt-integration.ru/T/

v2: Add 2 patches. Also make sure to commit against latest
netdev/net.

Ivan Abramov (3):
  cfg80211: Restore initial state on failed device_rename() in
    cfg80211_switch_netns()
  cfg80211: Avoid calling WARN_ON() on -ENOMEM in
    cfg80211_switch_netns()
  cfg80211: Remove WARN_ON() in cfg80211_pernet_exit()
