update connector to wrong drm_device

Hello team!

Recently, I read the weston source code, and a possible error was found in a piece of code.

static void
drm_backend_update_connectors(struct drm_device *device,
			      struct udev_device *drm_device)
{
    ...

    assert(head == NULL || writeback == NULL);

    if (head) {
	ret = drm_head_update_info(head, conn);
	if (head->base.device_changed)
		drm_head_log_info(head, "updated");
	} else if (writeback) {
		ret = drm_writeback_update_info(writeback, conn);
	} else {
		ret = drm_backend_add_connector(b->drm, conn, drm_device);
	}
}

For the code ret = drm_backend_add_connector(b->drm, conn, drm_device); If both the head and writeback are NULL, then it should be add connector from the drm device passed by the function, not the b->drm device, this is because the weston is support multi-GPU, so I think it should be changed with:

ret = drm_backend_add_connector(device, conn, drm_device);

Is this right?
