Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next

Johan Hedberg say:

====================
pull request: bluetooth-next 2014-12-31

Here's the first batch of bluetooth patches for 3.20.

 - Cleanups & fixes to ieee802154  drivers
 - Fix synchronization of mgmt commands with respective HCI commands
 - Add self-tests for LE pairing crypto functionality
 - Remove 'BlueFritz!' specific handling from core using a new quirk flag
 - Public address configuration support for ath3012
 - Refactor debugfs support into a dedicated file
 - Initial support for LE Data Length Extension feature from Bluetooth 4.2

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