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

John W. Linville says:

====================
For the mac80211 bits, Johannes says:

"I have a fix from Javier for mac80211_hwsim when used with wmediumd
userspace, and a fix from Felix for buffering in AP mode."

For the NFC bits, Samuel says:

"This pull request only contains one fix for a regression introduced with
commit e29a9e2ae165620d. Without this fix, we can not establish a p2p link
in target mode. Only initiator mode works."

For the iwlwifi bits, Emmanuel says:

"It only includes new device IDs so it's not vital. If you have a pull
request to net.git anyway, I'd happy to have this in."
