Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless-next

John W. Linville says:

====================
This is a batch of updates intended for 3.7.  The ath9k, mwifiex,
and b43 drivers get the bulk of the commits this time, with a handful
of other driver bits thrown-in.  It is mostly just minor fixes and
cleanups, etc.

Also included is a Bluetooth pull, with a lot of refactoring.
Gustavo says:

	"These are the changes I queued for 3.7. There are a many
	small fixes/improvements by Andre Guedes. A l2cap channel
	refcounting refactor by Jaganath. Bluetooth sockets now
	appears in /proc/net, by Masatake Yamato and Sachin Kamat
	changes ours drivers to use devm_kzalloc()."
====================
