Subject: [PATCH net-next 00/13] Protect dev_kfree_skb_irq from NULL and remove unnecessary NULL checks
dev_kfree_skb_irq is not NULL safe. The following patch checks skb for NULL in
dev_kfree_skb_irq.
At many places we check for NULL before calling dev_kfree_skb_*(). Moving the
check to dev_kfree_skb_irq_*() removes the reddundant if condition and makes
code simpler.
Also dev_kfree_skb_any either calls dev_kfree_skb_irq or dev_kfree_skb
depending on where your code is running. dev_kfree_skb is NULL safe but
dev_kfree_skb_irq is not. This patch fixes it.
