Wen Yang ef86ea982b net: axienet: fix a potential double free in axienet_probe() ... There is a possible use-after-free issue in the axienet_probe(): 1701: np = of_parse_phandle(pdev->dev.of_node, "axistream-connected", 0); 1702: if (np) { ... 1787: of_node_put(np); ---> released here 1788: lp->eth_irq = platform_get_irq(pdev, 0); 1789: } else { ... 1801: } 1802: if (IS_ERR(lp->dma_regs)) { ... 1805: of_node_put(np); ---> double released here 1806: goto free_netdev; 1807: } We solve this problem by removing the unnecessary of_node_put().
