-                 * The following comment covers, why virtio cannot rely on it.
-                 *
-                 * Unlike the other virtual GPU drivers, virtio abstracts the
-                 * underlying bus type by using struct virtio_device.
-                 *
-                 * Hence the dev_is_pci() check, used in core DRM, will fail
-                 * and the unique returned will be the virtio_device "virtio0",
-                 * while a "pci:..." one is required.
-                 *
-                 * A few other ideas were considered:
-                 * - Extend the dev_is_pci() check [in drm_set_busid] to
-                 *   consider virtio.
-                 *   Seems like a bigger hack than what we have already.
-                 *
-                 * - Point drm_device::dev to the parent of the virtio_device
-                 *   Semantic changes:
-                 *   * Using the wrong device for i2c, framebuffer_alloc and
-                 *     prime import.
-                 *   Visual changes:
-                 *   * Helpers such as DRM_DEV_ERROR, dev_info, drm_printer,
-                 *     will print the wrong information.
-                 *
-                 * We could address the latter issues, by introducing
-                 * drm_device::bus_dev, ... which would be used solely for this.
-                 *
-                 * So for the moment keep things as-is, with a bulky comment
-                 * for the next person who feels like removing this
-                 * drm_dev_set_unique() quirk.
