net: ns83820: use dev_kfree_skb_irq instead of kfree_skb
It is not allowed to call kfree_skb() from hardware interrupt context or with interrupts being disabled, spin_lock_irqsave() make sure always in irq disable context. So the kfree_skb() should be replaced with dev_kfree_skb_irq(). This is detected by Coccinelle semantic patch. Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com> Signed-off-by: David S.
