Subject: [PATCH 9/9] tile: dma_debug: add debug_dma_mapping_error support
Date: Fri, 23 Nov 2012 14:37:54 -0700 [thread overview]
Message-ID: <1353706674.5270.105.camel@lorien2> (raw)
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.
