![]() static int greth_of_remove(struct platform_device *of_dev)
{
...
struct greth_private *greth = netdev_priv(ndev);
...
unregister_netdev(ndev);
free_netdev(ndev);
of_iounmap(&of_dev->resource[0], greth->regs, resource_size(&of_dev->resource[0]));
...
}
greth is netdev private data, but it is used
after free_netdev(). It can cause use-after-free when accessing greth
pointer. So, fix it by moving free_netdev() after of_iounmap()
call.
