====================
pull request: bluetooth-next 2015-10-28

Here are a some more Bluetooth patches for 4.4 which collected up during
the past week. The most important ones are from Kuba Pawlak for fixing
locking issues with SCO sockets. There's also a fix from Alexander Aring
for 6lowpan, a memleak fix from Julia Lawall for the btmrvl driver and
some cleanup patches from Marcel.

Please let me know if there are any issues pulling. Thanks.
