====================
pull request: bluetooth-next 2019-05-05

Here's one more bluetooth-next pull request for 5.2:

 - Fixed Command Complete event handling check for matching opcode
 - Added support for Qualcomm WCN3998 controller, along with DT bindings
 - Added default address for Broadcom BCM2076B1 controllers

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