https://git.kernel.org/linus/64dc5d5e341d ("Revert "wifi: iwlwifi:
make no_160 more generic"") appeared in v6.15-rc5 and reverts
75a3313f52b7 ("wifi: iwlwifi: make no_160 more generic"), so it
*looks* like this regression should be fixed, but it still appears in
the tracker at https://linux-regtracking.leemhuis.info/regzbot/mainline/

If it is resolved, can somebody send the appropriate regzbot fix
command?  (See https://linux-regtracking.leemhuis.info/about/#tldr)
