Subject: net: arc_emac: use dev_kfree_skb_any instead of dev_kfree_skb
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=0f6e87613c3234c6350aaa971bd9434d29405302;p=linux-beck.git

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.
