3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Russ Gorby <russ.gorby@xxxxxxxxx>
commit 329e56780e514a7ab607bcb51a52ab0dc2669414 upstream.
Drivers are supposed to use the dev_* versions of the kfree_skb
interfaces. In a couple of cases we were called with IRQs
disabled as well which kfree_skb() does not expect.
Replaced kfree_skb calls w/ dev_kfree_skb and dev_kfree_skb_any
