Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next
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. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
