Merge branch 'wireless' 

John W. Linville says:

====================
This batch of fixes is intended for 3.8...

Included is a Bluetooth pull.  Gustavo says:

"A few fixes for 3.8. Five of them are just new devices ids addition.
Apart from the that there is fix to a kernel memory leak to userspace from
Anderson Lizardo, two interoperability fixes from Jaganath Kanakkassery and
Szymon Janc. And a crash fix by me."

Along with that, Amitkumar Karwar brings a pair of mwifiex fixes for
problems related to handling of band information within the driver.
These problems can lead to association failures.

Sujith Manoharan fixes a memory leak in the ath9k_htc code (originally
reported by Larry Finger).

The big hero this round is Felix Fietkau.  Felix gives us seven
ath9k fixes, including a fix for a race condition, the removal of a
double-free, and a fix for a deadlock, among others.

These have all been in linux-next for at least a couple of days,
with no complaints so far.  Please let me know if there are problems!
