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

Johan Hedberg says:

====================
Here's another set of Bluetooth & ieee802154 patches intended for 4.1:

 - Added support for QCA ROME chipset family in the btusb driver
 - at86rf230 driver fixes & cleanups
 - ieee802154 cleanups
 - Refactoring of Bluetooth mgmt API to allow new users
 - New setting for static Bluetooth address exposed to user space
 - Refactoring of hci_dev flags to remove limit of 32
 - Remove unnecessary fast-connectable setting usage restrictions
 - Fix behavior to be consistent when trying to pair already paired device
 - Service discovery corner-case fixes

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