No conflicts at the time of writing. There were conflicts with

Hmm. I already merged this earlier, but didn't notice a new warning on
my desktop:

They all seem to have that same issue, and it looks like the fix would
be to get the RTN lock in iwl_mvm_init_mcc(), but I didn't really look
into it very much.

This is on my desktop, and I actually don't _use_ the wireless on this
machine. I assume it still works despite the warnings, but they should
get fixed.

I *don't* see these warnings on my laptop where I actually use
wireless, but that one uses ath10k_pci, so it seems this is purely a
iwlwifi issue.

I can't be the only one that sees this. Hmm?

Mm. Looking thru the recent commits there is a suspicious rtnl_unlock()
in commit eb09ae93dabf ("iwlwifi: mvm: load regdomain at INIT stage").
