sparc: 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. Signed-off-by: Shuah Khan <shuah.khan@hp.com> Acked-by: David S.
