    drm/kms/fb: add polling support for when nothing is connected. · 5c4426a7

    When we are running in a headless environment we have no idea what
    output the user might plug in later, we only have hotplug detect
    from the digital outputs. So if we detect no connected outputs at
    initialisation, start a slow work operation to poll every 5 seconds
    for an output.
    
    this is only hooked up for radeon so far, on hw where we have full
    hotplug detection there is no need for this.
