Merge tag 'mac80211-for-net-2021-01-26' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211
Johannes Berg says:
====================
A couple of fixes:
* fix 160 MHz channel switch in mac80211
* fix a staging driver to not deadlock due to some
recent cfg80211 changes
* fix NULL-ptr deref if cfg80211 returns -EINPROGRESS
to wext (syzbot)
* pause TX in mac80211 in type change to prevent crashes
(syzbot)
* tag 'mac80211-for-net-2021-01-26' of git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211:
staging: rtl8723bs: fix wireless regulatory API misuse
mac80211: pause TX while changing interface type
wext: fix NULL-ptr-dereference with cfg80211's lack of commit()
mac80211: 160MHz with extended NSS BW in CSA
