====================
pull request: bluetooth-next 2016-03-01

Here's our main set of Bluetooth & 802.15.4 patches for the 4.6 kernel.

 - New Bluetooth HCI driver for Intel/AG6xx controllers
 - New Broadcom ACPI IDs
 - LED trigger support for indicating Bluetooth powered state
 - Various fixes in mac802154, 6lowpan and related drivers
 - New USB IDs for AR3012 Bluetooth controllers

Please let me know if there are any issues pulling. Thanks.
