From 81ad2b7de6dd352802f9979910343d4867e1ac94 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Thu, 20 Oct 2016 17:00:32 +0000 Subject: [PATCH] net: ethernet: mediatek: use dev_kfree_skb_any instead of dev_kfree_skb Replace dev_kfree_skb with dev_kfree_skb_any in mtk_start_xmit() which can be called from hard irq context (netpoll) and from other contexts. mtk_start_xmit() only frees skbs that it has dropped. This is detected by Coccinelle semantic patch. Signed-off-by: Wei Yongjun Signed-off-by: David S.
