====================
pull request: bluetooth-next 2015-02-03

Here's what's likely the last bluetooth-next pull request for 3.20.
Notable changes include:

 - xHCI workaround + a new id for the ath3k driver
 - Several new ids for the btusb driver
 - Support for new Intel Bluetooth controllers
 - Minor cleanups to ieee802154 code
 - Nested sleep warning fix in socket accept() code path
 - Fixes for Out of Band pairing handling
 - Support for LE scan restarting for HCI_QUIRK_STRICT_DUPLICATE_FILTER
 - Improvements to data we expose through debugfs
 - Proper handling of Hardware Error HCI events

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