====================
pull request: linux-bluetooth 2019-11-11

Here's one more bluetooth-next pull request for the 5.5 kernel release.

 - Several fixes for LE advertising
 - Added PM support to hci_qca driver
 - Added support for WCN3991 SoC in hci_qca driver
 - Added DT bindings for BCM43540 module
 - A few other small cleanups/fixes
====================
