[PATCH 6/9] powerpc: dma_debug: add debug_dma_mapping_error support

From: Shuah Khan
Date: Fri Nov 23 2012 - 16:35:33 EST


Add dma-debug interface debug_dma_mapping_error() to debug drivers that fail
to check dma mapping errors on addresses returned by dma_map_single() and
dma_map_page() interfaces.
