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

John W. Linville says:

====================
Here are some more fixes intended for the 3.9 stream...

Regarding the mac80211 bits, Johannes says:

"I had changed the idle handling to simplify it, but broken the
sequencing of commands, at least for ath9k-htc, one patch restores the
sequence. The other patch fixes a crash Jouni found while stress-testing
the remain-on-channel code, when an item is deleted the work struct can
run twice and crash the second time."

As for the iwlwifi bits, Johannes says:

"The only fix here is to the passive-no-RX firmware regulatory
enforcement driver support code to not drop auth frames in quick
succession, leading to not being able to connect to APs on passive
channels in certain circumstances."

Don't forget the NFC bits, about which Samuel says:

"This time we have:

- A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter
  is physically removed.
- A potential double skb free when the LLCP socket receive queue is full.
- A fix for properly handling multiple and consecutive LLCP connections, and
  not trash the socket ack log.
- A build failure for the MEI microread physical layer, now that the MEI bus
  APIs have been merged into char-misc-next."

On top of that, Stone Piao provides an mwifiex fix to avoid accessing
beyond the end of a buffer.
