Johan Hedberg says:

====================
pull request: bluetooth-next 2015-08-28

One more bunch of Bluetooth patches for 4.3:

 - Crash fix for hci_bcm driver
 - Enhancements to hci_intel driver (e.g. baudrate configuration)
 - Fix for SCO link type after multiple connect attempts
 - Cleanups & minor fixes in a few other places

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