    Bluetooth: Restrict access for raw-only controllers · fee746b0
    Marcel Holtmann authored
    Bluetooth controllers that are marked for raw-only usage can only be
    used with user channel access. Any other operation should be rejected.
    
    This simplifies the whole raw-only support since it now depends on
    the fact that the controller is marked with HCI_QUIRK_RAW_DEVICE and
    runtime raw access is restricted to user channel operation.
    
    The kernel internal processing of HCI commands and events is designed
    around the case that either the kernel has full control over the device
    or that the device is driven from userspace. This now makes a clear
    distinction between these two possible operation modes.
