====================
pull request: bluetooth-next 2015-07-30

Here's a set of Bluetooth & 802.15.4 patches intended for the 4.3 kernel.

 - Cleanups & fixes to mac802154
 - Refactoring of Intel Bluetooth HCI driver
 - Various coding style fixes to Bluetooth HCI drivers
 - Support for Intel Lightning Peak Bluetooth devices
 - Generic class code in interface descriptor in btusb to match more HW
 - Refactoring of Bluetooth HS code together with a new config option
 - Support for BCM4330B1 Broadcom UART controller

Let me know if there are any issues pulling. Thanks.
