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

John W. Linville says:

====================
Please pull this last(?) batch of fixes intended for 3.6...

For the Bluetooth bits, Gustavo says this:

"Here goes probably my last update to 3.6. It includes the two patches
you were ok last week(from Andrzej Kaczmarek), those are critical
ones, and two other fixes one for a system crash and the other for
a missing lockdep annotation."

The referenced fixes from Andrzej prevent attempts to configure devices
that are powered-off.

Along with the Bluetooth fixes, there are a couple of 802.11 fixes.
Emmanuel Grumbach gives us an iwlwifi fix to prevent releasing an
interrupt twice.  Luis R. Rodriguez provides a fix for a possible
circular lock dependency in the cfg80211 regulatory enforcement code.

All of these have been in linux-next for a few days.  I hope they are
not too late to make the 3.6 release!
====================
