Async\nconnections are zero-allocated, so the list entry still has NULL next\nand prev pointers on this path. Calling list_del() on it can therefore\ndereference NULL instead of returning the original link creation error.\n\nDo not delete asc_subdev_entry from err_call_unbind. There is no list\ninsertion to undo on this path; the bound callback and sub-device\nregistration are the operations that need to be rolled back."
