linux-next: manual merge of the wireless-current tree with a fix up patch

[Stephen Rothwell]

Hi John,

Today's linux-next merge of the wireless-current tree got a conflict in
drivers/net/wireless/ath/ar9170/usb.c between a fix I am carrying in the
linux-next tree and commit 160b82420ab41f1e67fbf2e56dc587837ef39ce0
("ar9170: wait for asynchronous firmware loading") from the
wireless-current tree.

I fixed it up (see at the bottom or this email).

John, can you put this following small patch in your wireless-current
tree, please?  This is to cope with an upcoming API change and applies to
Linus' tree (the device_lock/unlock wrappers are already in Linus' tree).
