In order to de-const variables simply casting through (void *) is not enough: "cast from 'const .. *' to 'void *' drops const qualifier". Cast through (uintptr_t) as well [1] to make this compile on systems with more strict requirements. In addition passing const void *data to dma_map_single() also drops the (const) qualifier. De-constify on variable on assignment which may be overwritten later. In either case the (void *) cast to dma_map_single() is not needed (anymore) either.
