I don't understand this. In i2c-rockchip.c we have:

        i2c->adapter.dev.parent = dev;
        i2c->adapter.dev.of_node = dev->of_node;
	i2c_add_numbered_adapter(&i2c->adapter);

With that it shouldn't make a difference whether we do this:

adapter->nr = of_alias_get_id(adapter->dev.parent->of_node, "i2c");

or that:

adapter->nr = of_alias_get_id(adapter->dev->of_node, "i2c");

Should be the same device node both times.
