Subject: mac80211/ath11k regression in next-20220720

Hi,

After moving from next-20220714 to next-20220720, ath11k stopped
working here and instead spits out a bunch of warnings (see log below).

I noticed that this series from Johannes was merged in that period:

	https://lore.kernel.org/all/20220713094502.163926-1-johannes@sipsolutions.net/

but can't say for sure that it's related. I also tried adding the
follow-up fixes from the mld branch:

	https://git.kernel.org/pub/scm/linux/kernel/git/wireless/wireless-next.git/log/?h=mld

but it didn't seem to make any difference.

Any ideas about what might be going on here?

Johan
