====================
pull request: bluetooth-next 2018-08-10
Here's one more (most likely last) bluetooth-next pull request for the
4.19 kernel.
- Added support for MediaTek serial Bluetooth devices
- Initial skeleton for controller-side address resolution support
- Fix BT_HCIUART_RTL related Kconfig dependencies
- A few other minor fixes/cleanups
Please let me know if there are any issues pulling. Thanks.
