PATCH 1/1 powerpc: dma-mapping: support debug_dma_mapping_error

Add support for debug_dma_mapping_error() call to avoid warning from debug_dma_unmap() interface when it checks for mapping error checked status. Without this patch, device driver failed to check map error warning is generated.

This one is for powerpc to go through your tree with the other arch debug_dma_mapping_error() patches.

Thanks,
