Johan Hedberg says:
====================
pull request: bluetooth-next 2015-05-28
Here's a set of patches intended for 4.2. The majority of the changes
are on the 802.15.4 side of things rather than Bluetooth related:
- All sorts of cleanups & fixes to ieee802154 and related drivers
- Rework of tx power support in ieee802154 and its drivers
- Support for setting ieee802154 tx power through nl802154
- New IDs for the btusb driver
- Various cleanups & smaller fixes to btusb
- New btrtl driver for Realtec devices
- Fix suspend/resume for Realtek devices
Please let me know if there are any issues pulling. Thanks.
