(cherry picked from commit 0331b8e990ed1004f427ef6037ebd8079f3c97fc
git://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git master)

Conflicts: drivers/bluetooth/btintel.c
           drivers/bluetooth/btusb.c
Note: a large refactoring was performed in upstream. Hence, the
      changes applied to btintel.c were applied to btusb.c instead.
