Subject: [PATCH -next] dwc_eth_qos: use dev_kfree_skb_any instead of dev_kfree_skb

From: Wei Yongjun <weiyongjun1@...wei.com>

Replace dev_kfree_skb with dev_kfree_skb_any in dwceqos_start_xmit()
which can be called from hard irq context (netpoll) and from
other contexts. dwceqos_start_xmit() only frees skbs that it has
dropped.

This is detected by Coccinelle semantic patch.
