Merge branch 'for-upstream' of git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth
Johan Hedberg says: ==================== pull request: bluetooth 2016-11-23 Sorry about the late pull request for 4.9, but we have one more important Bluetooth patch that should make it to the release. It fixes connection creation for Bluetooth LE controllers that do not have a public address (only a random one). Please let me know if there are any issues pulling. Thanks. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
