Hi Jakub,

And for mac80211-next, I have only locking fixes right now. I'm
happy that it otherwise seems to be fine though, now no new bugs
have been reported for a few days.

I might send some more things your way another day, but wanted
to get the locking fixes out sooner.

Please pull and let me know if there's any problem.

Thanks,
johannes

  cfg80211: fix netdev registration deadlock (2021-02-01 19:30:54 +0100)

----------------------------------------------------------------
This time, only RTNL locking reduction fallout.
 - cfg80211_dev_rename() requires RTNL
 - cfg80211_change_iface() and cfg80211_set_encryption()
   require wiphy mutex (was missing in wireless extensions)
 - cfg80211_destroy_ifaces() requires wiphy mutex
 - netdev registration can fail due to notifiers, and then
   notifiers are "unrolled", need to handle this properly

----------------------------------------------------------------
Johannes Berg (5):
      nl80211: call cfg80211_dev_rename() under RTNL
      wext: call cfg80211_change_iface() with wiphy lock held
      wext: call cfg80211_set_encryption() with wiphy lock held
