Specific engine driver may use this module. CONFIG_NEED_SG_DMA_LENGTH shouldn't be set by an arbitrary driver - the arch code will set this if needed, and if it doesn't, the additional dma_length field shouldn't be expected to have a meaning. If you are fixing a COMPILE_TEST failure, just add NEED_SG_DMA_LENGTH as a dependency, or drop the COMPILE_TEST altogether (why was that added in the first place?)

Because we want to maximise compiler coverage so that build failures can be caught at the earliest opportunity. But a better fix would be to use sg_dma_len(sg) instead of sg->dma_length Cheers,
