yam: fix possible memory leak in yam_init_driver
If register_netdev(dev) fails, free_netdev(dev) needs to be called, otherwise a memory leak will occur. Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Reported-by: Hulk Robot <hulkci@huawei.com> Signed-off-by: Wang Hai <wanghai38@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net>
