In the process of building a custom kernel with 4.14.X the user executes make odroidxu4_defconfig. In this configuration the "Device Driver" -> "Multimedia" ist build into the kernel and NOT as a module. Due to this, it's impossible to use media_build *) to get support for newer DVB cards. The configuration results in a conflict and the user gets "duplicated exported symbol".
Please change the "Device Driver" -> "Multimedia" to build as a module. With that change media_build can be used without further changes in the kernel.
