Hi,

Here's the first wireless pull request, see below.

Now that I'm actually preparing this, I'm having second
thoughts on the debugfs lockdep change, since that's a
new 'feature' of sorts, pointing out the deadlocks. I had
that in to actually sort of prove the fix worked, though
I also tested that another way, Greg ACK'ed it, and then
I didn't think about it again. I guess I could revert it
back out, but it doesn't revert cleanly. Lockdep only.

Also there was a fortify build problem report on the CQM
fix that we haven't been able to make sense of, and yet
the CQM fix is the one thing we'd rather have in soon as
it broke quite a few users... Asked Kees about it too,
but no response yet (it was only this morning.)

If that seems OK for now, please pull. Otherwise let me
know if I should revert the debugfs lockdep, and/or wait
for the CQM/fortify issue to get resolved.

Thanks,
johannes

  wifi: mac80211: use wiphy locked debugfs for sdata/link (2023-11-27 11:25:09 +0100)

----------------------------------------------------------------
wireless fixes:
 - debugfs had a deadlock (removal vs. use of files),
   fixes going through wireless ACKed by Greg
 - support for HT STAs on 320 MHz channels, even if it's
   not clear that should ever happen (that's 6 GHz), best
   not to WARN()
 - fix for the previous CQM fix that broke most cases
 - various wiphy locking fixes
 - various small driver fixes
