Since mt76_set_channel() also acquires\ndev-\u003emutex, this results in a deadlock.\n\nUse __mt76_set_channel() instead of mt76_set_channel().\nAdd cancel_delayed_work_sync() for mac_work before acquiring the mutex\nin mt76_remain_on_channel() to prevent a secondary deadlock with the\nmac_work workqueue.",
