Here's another set of Bluetooth & 802.15.4 patches for the 4.7 kernel:
- Cleanups & refactoring of ieee802154 & 6lowpan code
- Security related additions to ieee802154 and mrf24j40 driver
- Memory corruption fix to Bluetooth 6lowpan code
- Race condition fix in vhci driver
- Enhancements to the atusb 802.15.4 driver
Please let me know if there are any issues pulling. Thanks.
