The build of m32r allmodconfig fails with the error: drivers/media/v4l2-core/videobuf2-dma-contig.c:492:28: error: implicit declaration of function 'dma_get_cache_alignment' The build of videobuf2-dma-contig.c depends on HAS_DMA and it is correctly mentioned in the Kconfig but the symbol VIDEO_TI_CAL also selects VIDEOBUF2_DMA_CONTIG, so it is trying to compile videobuf2-dma-contig.c even though HAS_DMA is not defined.
