On an empty list it returns\ncontainer_of() of the list head. So the \"if (!config)\" check is dead.\n\nWhen cdev->configs is empty, config points at the head inside struct\nusb_composite_dev. config->descriptors[0] reads whatever sits at that\noffset. The memcpy copies up to w_length bytes of it into the response\nbuffer.\n\ncdev->configs can be empty in two cases. One is a teardown race on\ngadget unbind with a control transfer in flight.
