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.
