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

John W. Linville says:

====================
Here is another batch of updates intended for 3.7...

Highlights include an hci_connect re-write in Bluetooth, HCI/LLC
layer separation in NFC, removal of the raw pn544 NFC driver, NFC LLCP
raw sockets support, improved IBSS auth frame handling in mac80211,
full-MAC AP mode notification support in mac80211, a lot of attention
paid to brcmfmac, and the usual level of updates to iwlwifi, ath9k,
mwifiex, and rt2x00, and various other updates.
====================
