====================
pull request: bluetooth-next 2015-03-02

Here's the first bluetooth-next pull request targeting the 4.1 kernel:

 - ieee802154/6lowpan cleanups
 - SCO routing to host interface support for the btmrvl driver
 - AMP code cleanups
 - Fixes to AMP HCI init sequence
 - Refactoring of the HCI callback mechanism
 - Added shutdown routine for Intel controllers in the btusb driver
 - New config option to enable/disable Bluetooth debugfs information
 - Fix for early data reception on L2CAP fixed channels

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