By our submission guidelines and requests from Linus this afaics should
also contain:

Reported-by: Klara Modin <[email protected]>
Closes: https://lore.kernel.org/all/[email protected]/
Reported-by: Tobias Klausmann <[email protected]>
Closes:
https://lore.kernel.org/linux-wireless/[email protected]/

Both of them now CCed, too, to give them a chance to provide a "Tested-by:".

> Fixes: 31ee1582717e ("wifi: mt76: fix of_get_mac_address error handling")

Given this and the reports linked above this afaics should also be
tagged with "wireless", and not with "wireless-next", as this commit is
in 7.2-rc1 -- and thus ideally should be fixed by now. See
https://www.kernel.org/doc/html/latest/process/handling-regressions.html#on-how-quickly-regressions-should-be-fixed,
which contains links to these quotes from Linus:

""But a user complaining should basically result in an immediate fix -
possibly a "revert and rethink"."" and ""It's also worth noting that
"immediate" obviously doesn't mean "right this *second* when the problem
has been reported". But if it's a regression with a known commit that
caused it, I think the rule of thumb should generally be "within a
week", preferably before the next rc.""

Ciao, Thorsten
