====================
pull request: bluetooth-next 2015-01-16

Here are some more bluetooth & ieee802154 patches intended for 3.20:

 - Refactoring & cleanups of ieee802154 & 6lowpan code
 - Various fixes to the btmrvl driver
 - Fixes for Bluetooth Low Energy Privacy feature handling
 - Added build-time sanity checks for sockaddr sizes
 - Fixes for Security Manager registration on LE-only controllers
 - Refactoring of broken inquiry mode handling to a generic quirk

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