Hey folks,

[ 9.071626] wlcore: ERROR unable to register mac80211 hw: -22
Which seems to be caused by commit 901bb9891855 ("nl80211: require and
validate vendor command policy"), and I've validated that reverting
that gets it working again.
It seems like from the commit message, the wlcore driver isn't
providing the policy values the network core expects? I'm not sure
what the right fix would be, but wanted to raise the issue.
Suggestions?
thanks

There's a fix on the way, unfortunately I forgot to send the pull
request before the merge window. I sent it out a couple of days ago and
narrowly missed -rc1, but it'll be in rc2:
