Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next
Johan Hedberg says: ==================== pull request: bluetooth-next 2015-08-16 Here's what's likely the last bluetooth-next pull request for 4.3: - 6lowpan/802.15.4 refactoring, cleanups & fixes - Document 6lowpan netdev usage in Documentation/networking/6lowpan.txt - Support for UART based QCA Bluetooth controllers - Power management support for Broeadcom Bluetooth controllers - Change LE connection initiation to always use passive scanning first - Support for new Silicon Wave USB ID Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
