Subject: pull request: wireless 2013-03-15

Dave,

Please pull these fixes for the 3.9 stream.

On the NFC bits, Samuel says:

"With this one we have:

- A fix for properly decreasing socket ack log.
- A timer and works cleanup upon NFC device removal.
- A monitoroing socket cleanup round from llcp_socket_release.
- A proper error report to pending sockets upon NFC device removal."

Regarding the Bluetooth bits, Gustavo says:

"I have these two patches for 3.9, these add support for two more devices to
the bluetooth drivers."

Along with those, we have a few wireless driver fixes...

Bing Zhao provides an mwifiex to prevent an out-of-bounds memory
access.

John Crispin offers a Kconfig fix to enable some otherwise dead code
in rt2x00.  The correct symbols were added in -rc1 through a different
tree, but the symbols for enabling the wireless driver didn't match.

Larry Finger brings an rtlwifi fix for a scheduling while atomic bug,
and another fix for a reassociation problem caused by failing to
clear the BSSID after a disconnect.

Please let me know if there are problems!

Thanks,

John
