A driver doesn't allocate a target. In this code, a target device is
purely a LUN container and is managed by the mid-layer. The driver
requests the scan of a target by parent device, channel and id. This
request for a scan creates and parents the target object, but reaps it
again if no actual LUNs are discovered.
