Subjectpull request: wireless 2013-09-27
Dave,

Please pull this batch of fixes intended for the 3.12 stream!

Regarding the Bluetooth bits, Gustavo says:

"First Bluetooth fixes to 3.12, it includes:

* 3 patches to add device id for 3 new hardwares.

* 2 patches from Johan to fix the rfkill behaviour during setup stage

* a small clean up in the rfcomm TTY code that fixes a potential racy
condition (by Gianluca Anzolin)

* 2 fixes to proper set encryption key size and security level in the
peripheral role of Bluetooth LE devices. (by Andre Guedes)

* a fix for dealing devices where pairing is not necessary, we were keeping
the Bluetooth ACL connection alive for too much time. (by Syam Sidhardhan)"

Also, I fixed-up an curly-brace indentation problem in the Bluetooth
code while merging. On top of that...

Alexey Khoroshilov brings a p54usb fix to avoid a resource leak when
request_firmware_nowait fails.

Amitkumar Karwar fixes a firmware hang caused by too much header data
being appended for USB devices using the mwifiex driver.

Arend van Spriel provides three fixes: a brcmfmac fix to relocate some
driver code outside of an .init section; a scheduling while atomic
fix for bcma; and, another scheduling while atomic fix for brcmsmac.

Bing Zhao offers a pair of mwifiex fixes: a code change to avoid
firmware timeouts on USB; and a fix for a NULL pointer dereference.

Christian Lamparter adds a device ID to p54usb.

Felix Fietkau implements a quartet of small ath9k fixes, including
a locking fix, a list management fix, a fix to properly mark a stale
buffer, and an aggregate buffering fix.

Larry Finger champions a data alignment fix to make rtlwifi work
better with ARM builds.

Solomon Peachy reverts an earlier interrupt handling fix for cw1200
and replaces it with a new threaded oneshot irq handler implementation.

Sujith Manoharan fixes an ath9k regression by reverting an earlier
patch.

Please let me know if there are problems!

John
