There's a different patch referenced in the dashboard https://groups.google.com/g/syzkaller-lts-bugs/c/ntHpclbYBMM/m/WG3hW1DvAgAJ commit 25487a5ff100398cb214ae854358609e4bbd4e7d Author: Johannes Berg Date: Mon May 17 14:47:17 2021 +0000 mac80211: remove warning in ieee80211_get_sband() that looks more relevant but I don't know if it's the real fix.
