Subject: pcnet32: Call dev_kfree_skb_any instead of dev_kfree_skb.
X-Git-Tag: firefly_0821_release~176^2~4167^2~96^2~45
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=af9ba92cb2e8874ec35055212b15be044cb96e3c;p=firefly-linux-kernel-4.4.55.git

pcnet32: Call dev_kfree_skb_any instead of dev_kfree_skb.

Replace dev_kfree_skb with dev_kfree_skb_any in pcnet32_start_xmit
that can be called in hard irq and other contexts.

dev_kfree_skb_any is used as pcnet32_start_xmit only frees an
skb when it drops a packet during transmit.
