Subject: dwc_eth_qos: use dev_kfree_skb_any instead of dev_kfree_skb
X-Git-Tag: v4.14-rc1~1973^2~429

dwc_eth_qos: use dev_kfree_skb_any instead of dev_kfree_skb

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.
