[XTENSA]: Fix use of skb after netif_rx
Recently, Wang Chen submitted a patch (d30f53aeb31d453a5230f526bea592af07944564) to move a call to netif_rx(skb) after a subsequent reference to skb, because netif_rx may call kfree_skb on its argument. The same problem occurs in some other drivers as well. This was found using the following semantic match. (http://www.emn.fr/x-info/coccinelle/) // <smpl> @@ expression skb, e,e1; @@ ( netif_rx(skb); | netif_rx_ni(skb); ) ... when != skb = e ( skb = e1 | * skb ) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: David S. Miller <davem@davemloft.net>
