====================
pull request: bluetooth-next 2015-05-04

Here's the first bluetooth-next pull request for 4.2:

 - Various fixes for at86rf230 driver
 - ieee802154: trace events support for rdev->ops
 - HCI UART driver refactoring
 - New Realtek IDs added to btusb driver
 - Off-by-one fix for rtl8723b in btusb driver
 - Refactoring of btbcm driver for both UART & USB use

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