PATCH 1/1 sh: 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.

Marek,

This one is for sh to go through tree with the other arch dma_debug_dma_mapping_error() change patches.

Thanks,
