From 0f6e87613c3234c6350aaa971bd9434d29405302 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 19 Oct 2016 13:47:52 +0000 Subject: net: arc_emac: use dev_kfree_skb_any instead of dev_kfree_skb Replace dev_kfree_skb with dev_kfree_skb_any in arc_emac_tx() which can be called from hard irq context (netpoll) and from other contexts. arc_emac_tx() only frees skbs that it has dropped. This is detected by Coccinelle semantic patch. Signed-off-by: Wei Yongjun Signed-off-by: David S.
