All architectures except arm that define DMA_ERROR_CODE are casting it to (dma_addr_t) - as it is always compared to dma_addr_t in arm as well this could be harmonized.
Signed-off-by: Nicholas Mc Guire <[email protected]> --- This also fixes the build warning in ./arch/arm/include/asm/dma-mapping.h: In function 'dma_mapping_error': ./arch/arm/include/asm/dma-mapping.h:176:18: warning: comparison between signed and unsigned integer expressions [-Wsign-compare] While it fixes this build warning it causes another build warning - so from that perspective its not much of an improvement - never the less having this harmonized with all other archs makes sense I think.
