====================
pull request: bluetooth-next 2018-08-05

Here's the main bluetooth-next pull request for the 4.19 kernel.

 - Added support for Bluetooth Advertising Extensions
 - Added vendor driver support to hci_h5 HCI driver
 - Added serdev support to hci_h5 driver
 - Added support for Qualcomm wcn3990 controller
 - Added support for RTL8723BS and RTL8723DS controllers
 - btusb: Added new ID for Realtek 8723DE
 - Several other smaller fixes & cleanups

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