By adding a print statement to drivers/media/v4l2-core/v4l2-async.c in the v4l2_async_register_subdev function, I can confirm that there is no match found. Specifically, this block starting on line 756 is executed:

	/* None matched, wait for hot-plugging */
	list_add(&sd->async_list, &subdev_list);
    if (strcmp(sd->name, "adv7180 9-0021") == 0)
    {
        pr_notice("adv7180 v4l2_async_register_subdev -- no match found\n");
    }

What does that mean? How can I dig into this further? Thanks.
