Hey Sukrut, When you make code that deletes something from the kernel, you need to make sure that all other code that references that code will still function properly. When you surround things in the #ifdev, depending on the config file, the compiler strips those things out and compiles without them. That means that you actually need to compile and test under two conditions. Once when CONFIG_FB_DEVICE=y and another time when CONFIG_FB_DEVICE=n. The test robot gave you a sample config file that you can use. Please ensure that you have the proper version of Clang on your Host machine for that particular config file, if you choose to use it. Also, I strongly recommend that you run the code on a sufficient hardware or emulator after you test it so that you can verify that the code does what you think it does. Thanks, David Hunter
