Thanks a lot for the sharpen eyes. Yes. I do not need these empty callbacks. I have some program experience with Linux-4.19 kernel. I clearly remember that these empty callbacks was need when I add lt8619 display bridge driver. I have just remove it and tested, it seems that those is not need anymore. Thanks a lot for review, this problem will be fixed at the next version.
