====================
pull request: bluetooth-next 2017-10-19

Here's the first bluetooth-next pull request targeting the 4.15 kernel
release.

 - Multiple fixes & improvements to the hci_bcm driver
 - DT improvements, e.g. new local-bd-address property
 - Fixes & improvements to ECDH usage. Private key is now generated by
   the crypto subsystem.
 - gcc-4.9 warning fixes

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