A lock is missing to relaese in snull_get_tx_buffer

[ryancaicse]

The lock is missing to release at Line 143. Should it be a bug?

ldd3/snull/snull.c

Lines 139 to 150 in dd5c9c7

	spin_lock_irqsave(&priv->lock, flags);
	pkt = priv->ppool;
	if(!pkt) {
	PDEBUG("Out of Pool\n");
	return pkt;
	}
	priv->ppool = pkt->next;
	if (priv->ppool == NULL) {
	printk (KERN_INFO "Pool empty\n");
	netif_stop_queue(dev);
	}
	spin_unlock_irqrestore(&priv->lock, flags);
