If the subsequent call to\nqrtr_alloc_ctrl_packet() fails due to memory allocation failure, the\nfunction returns -ENOMEM without calling qrtr_node_release() to\nrelease the node reference.\n\nAdd qrtr_node_release(node) before returning on the allocation failure\npath to properly release the reference.",
