====================
pull request: bluetooth 2016-01-30
Here's a set of important Bluetooth fixes for the 4.5 kernel:
- Two fixes to 6LoWPAN code (one fixing a potential crash)
- Fix LE pairing with devices using both public and random addresses
- Fix allocation of dynamic LE PSM values
- Fix missing COMPATIBLE_IOCTL for UART line discipline
Please let me know if there are any issues pulling. Thanks.
