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

John W. Linville says:

====================
Alexey Khoroshilov provides a potential memory leak in rndis_wlan.

Bob Copeland gives us an ath5k fix for a lockdep problem.

Dan Carpenter fixes a signedness mismatch in at76c50x.

Felix Fietkau corrects a regression caused by an earlier commit that can
lead to an IRQ storm.

Lorenzo Bianconi offers a fix for a bad variable initialization in ath9k
that can cause it to improperly mark decrypted frames.

Rajkumar Manoharan fixes ath9k to prevent the btcoex time from running
when the hardware is asleep.

The remainder are Bluetooth fixes, about which Gustavo says:

	"Here goes some fixes for 3.6-rc1, there are a few fix to
	thte inquiry code by Ram Malovany, support for 2 new devices,
	and few others fixes for NULL dereference, possible deadlock
	and a memory leak."
====================
