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

Cheers,
Stephen Rothwell sfr@...b.auug.org.au
