Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next
Johan Hedberg says: ==================== pull request: bluetooth-next 2015-03-02 Here's the first bluetooth-next pull request targeting the 4.1 kernel: - ieee802154/6lowpan cleanups - SCO routing to host interface support for the btmrvl driver - AMP code cleanups - Fixes to AMP HCI init sequence - Refactoring of the HCI callback mechanism - Added shutdown routine for Intel controllers in the btusb driver - New config option to enable/disable Bluetooth debugfs information - Fix for early data reception on L2CAP fixed channels Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
