From: Julia Lawall <julia.law...@lip6.fr> On success, the function netdev_alloc_skb initializes the dev field of its result to its first argument, so this doesn't have to be done in the calling context.
The semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression skb,privn,e; @@ skb = netdev_alloc_skb(privn,...); ... when strict ( -skb->dev = privn; | ?skb = e ) // </smpl> Signed-off-by: Julia Lawall <julia.law...@lip6.fr> --- drivers/staging/rtl8712/rtl8712_recv.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/drivers/staging/rtl8712/rtl8712_recv.c b/drivers/staging/rtl8712/rtl8712_recv.c index ea96537..0723b2f 100644 --- a/drivers/staging/rtl8712/rtl8712_recv.c +++ b/drivers/staging/rtl8712/rtl8712_recv.c @@ -90,7 +90,6 @@ int r8712_init_recv_priv(struct recv_priv *precvpriv, struct _adapter *padapter) pskb = netdev_alloc_skb(padapter->pnetdev, MAX_RECVBUF_SZ + RECVBUFF_ALIGN_SZ); if (pskb) { - pskb->dev = padapter->pnetdev; tmpaddr = (addr_t)pskb->data; alignment = tmpaddr & (RECVBUFF_ALIGN_SZ-1); skb_reserve(pskb, (RECVBUFF_ALIGN_SZ - alignment)); @@ -1083,7 +1082,6 @@ static int recvbuf2recvframe(struct _adapter *padapter, struct sk_buff *pskb) alloc_sz += 6; pkt_copy = netdev_alloc_skb(padapter->pnetdev, alloc_sz); if (pkt_copy) { - pkt_copy->dev = padapter->pnetdev; precvframe->u.hdr.pkt = pkt_copy; skb_reserve(pkt_copy, 4 - ((addr_t)(pkt_copy->data) % 4)); -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
