linux-next: manual merge of the staging tree with the net-next tree

From: Stephen Rothwell
Date: Thu Mar 27 2014 - 01:10:02 EST

Hi Greg,

Today's linux-next merge of the staging tree got a conflict in
drivers/staging/wlags49_h2/wl_netdev.c between commit 8d4ade284a41
("wlags49_h2: Call dev_kfree/consume_skb_any instead of dev_kfree_skb")
from the net-next tree and commit fed3ffd8f7ef ("staging: wlags49_h2:
reindent wl_netdev.c") (and maybe others) from the staging tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
