Only the\nmmio queue ops implement that callback; on the mt7663 USB and SDIO\nbuses it is NULL, so a TXRX_NOTIFY there calls a NULL pointer in the RX\nworker. Same defect as the mt7921 and mt7925 patches in this series.\n\nDrop the event on non-mmio buses via mt76_is_mmio(), as in\ncommit 5683e1488aa9 (\"wifi: mt76: connac: do not check WED status for\nnon-mmio devices\")."
