Kalle Valo says:
====================
wireless fixes for v5.18
Second set of fixes for v5.18 and hopefully the last one. We have a
new iwlwifi maintainer, a fix to rfkill ioctl interface and important
fixes to both stack and two drivers.
* tag 'wireless-2022-05-11' of git://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless:
rfkill: uapi: fix RFKILL_IOCTL_MAX_SIZE ioctl request definition
nl80211: fix locking in nl80211_set_tx_bitrate_mask()
mac80211_hwsim: call ieee80211_tx_prepare_skb under RCU protection
mac80211_hwsim: fix RCU protected chanctx access
mailmap: update Kalle Valo's email
mac80211: Reset MBSSID parameters upon connection
cfg80211: retrieve S1G operating channel number
nl80211: validate S1G channel width
mac80211: fix rx reordering with non explicit / psmp ack policy
ath11k: reduce the wait time of 11d scan and hw scan while add interface
MAINTAINERS: update iwlwifi driver maintainer
iwlwifi: iwl-dbg: Use del_timer_sync() before freeing
