John W. Linville says:

====================
pull request: wireless-next 2014-06-02

Please pull this remaining batch of updates intended for the 3.16 stream...

For the mac80211 bits, Johannes says:

"The remainder for -next right now is mostly fixes, and a handful of
small new things like some CSA infrastructure, the regdb script mW/dBm
conversion change and sending wiphy notifications."

For the bluetooth bits, Gustavo says:

"Some more patches for 3.16. There is nothing really special here, just a
bunch of clean ups, fixes plus some small improvements. Please pull."

For the nfc bits, Samuel says:

"We have:

- Felica (Type3) tags support for trf7970a
- Type 4b tags support for port100
- st21nfca DTS typo fix
- A few sparse warning fixes"

For the atheros bits, Kalle says:

"Ben added support for setting antenna configurations. Michal improved
warm reset so that we would not need to fall back to cold reset that
often, an issue where ath10k stripped protected flag while in monitor
mode and made module initialisation asynchronous to fix the problems
with firmware loading when the driver is linked to the kernel.

Luca removed unused channel_switch_beacon callbacks both from ath9k and
ath10k. Marek fixed Protected Management Frames (PMF) when using Action
Frames. Also we had other small fixes everywhere in the driver."

Along with that, there are a handful of updates to a variety
of drivers.  This includes updates to at76c50x-usb, ath9k, b43,
brcmfmac, mwifiex, rsi, rtlwifi, and wil6210.
