Start with backports-5.15-rc6-1/net/mac80211/airtime.c at line 456 and trace the ieee80211_ocb_leave call path from the supplied stack trace. Use the mt76-tx context and the MiWiFi R3 hardware details to investigate the warning; done means identifying its cause and resolving it without introducing a regression.
