====================
pull request: bluetooth-next 2019-12-09

Here's the first bluetooth-next pull request for 5.6:

 - Devicetree bindings updates for Broadcom controllers
 - Add support for PCM configuration for Broadcom controllers
 - btusb: Fixes for Realtek devices
 - butsb: A few other smaller fixes (mem leak & non-atomic allocation issue)

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