Descriptions

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HCI: Remove HCI_AMP support Since BT_HS has been remove HCI_AMP controllers no longer has any use so
remove it along with the capability of creating AMP controllers. Since we no longer need to differentiate between AMP and Primary
controllers, as only HCI_PRIMARY is left, this also remove
hdev->dev_type altogether.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: Bluetooth: HCI: eliminar la compatibilidad con HCI_AMP Dado que se eliminó BT_HS, los controladores HCI_AMP ya no tienen ningún uso, así que elimínelos junto con la capacidad de crear controladores AMP. Como ya no necesitamos diferenciar entre los controladores AMP y primarios, ya que solo queda HCI_PRIMARY, esto también elimina hdev->dev_type por completo.
