A\nconcurrent I3C_NOTIFY_BUS_REMOVE can then unregister and free the bus\nnetdev before probe passes its private data to mctp_i3c_add_device().\nThe latter consequently adds a list node through a freed mbus pointer.\n\nKeep busdevs_lock held until the device has been added. This also\nsatisfies the __must_hold annotation on mctp_i3c_add_device().",
