pull request: bluetooth-next 2016-07-13

Here's our main bluetooth-next pull request for the 4.8 kernel:

 - Fixes and cleanups in 802.15.4 and 6LoWPAN code
 - Fix out of bounds issue in btmrvl driver
 - Fixes to Bluetooth socket recvmsg return values
 - Use crypto_cipher_encrypt_one() instead of crypto_skcipher
 - Cleanup of Bluetooth connection sysfs interface
 - New Authentication failure reson code for Disconnected mgmt event
 - New USB IDs for Atheros, Qualcomm and Intel Bluetooth controllers

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