[SRU Focal][PATCH 0/5] Address bluetooth security issues

Intel released an advisory on the bluetooth stack[1] that has a
collection of issues and recommendations. This set is a collection of
all those into Focal. Some will have to go into Bionic and Xenial but I
expect some changes will be needed. So I am submitting this just for
Focal to be a template for the backports.

Luiz Augusto von Dentz (4):
  Bluetooth: A2MP: Fix not initializing all members
    - note this appears to be present since v3.6
  Bluetooth: L2CAP: Fix calling sk_filter on non-socket based channel
    - note this appears to be present since v4.8
  Bluetooth: Disable High Speed by default
  Bluetooth: MGMT: Fix not checking if BT_HS is enabled

Stefan Bader (1):
  UBUNTU: [Config] Disable BlueZ highspeed support
    - note this turns off High Speed support in the driver. The related
      Intel patch claims this would only prevent use of higher speeds as
      feature. And that this would not be supported by hardware very
      often anyway. We might want to reconsider this later.
