It's not possible for ARCH_SUNXI or any other that depends on ARCH_MULTIPLATFORM. I just noticed that you have 'depends on ARCH_SUNXI', so the 'select DMA_OF' statement is just redundant, not wrong. However, if the driver was 'depends on ARCH_SUNXI || COMPILE_TEST' as many others are nowadays, it would be a bug.
