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.
