Kalle Valo says:

====================
wireless-drivers fixes for v5.12

Third, and last, set of fixes for v5.12. Small fixes, iwlwifi having
most of them. brcmfmac regression caused by cfg80211 changes is the
most important here.

iwlwifi

* fix a lockdep warning

* fix regulatory feature detection in certain firmware versions

* new hardware support

* fix lockdep warning

* mvm: fix beacon protection checks

mt76

* mt7921: fix airtime reporting

brcmfmac

* fix a deadlock regression
====================
