Johan Hedberg says:

====================
pull request: bluetooth-next 2017-07-01

Here are some more Bluetooth patches for the 4.13 kernel:

 - Added support for Broadcom BCM43430 controllers
 - Added sockaddr length checks before accessing sa_family
 - Fixed possible "might sleep" errors in bnep, cmtp and hidp modules
 - A few other minor fixes

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