Subject: macb: Call dev_kfree_skb_any instead of kfree_skb.
X-Git-Tag: v3.15-rc1~113^2~96^2~41
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c88b5b6a68da1bc4353521bde95246bbc0f85b5e;p=karo-tx-linux.git

macb: Call dev_kfree_skb_any instead of kfree_skb.

Replace kfree_skb with dev_kfree_skb_any in macb_start_xmit that can
be called in hard irq and other contexts.

macb_start_xmit only frees skbs when dropping them so
dev_kfree_skb_any is used.
