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.
