Revision fe73fbe1c5eda709084dedb66cbdd4b86826cce7 authored by Ming Lei on 19 October 2012, 20:57:01 UTC, committed by Linus Torvalds on 19 October 2012, 21:07:48 UTC
If there is only one match, the unique matched entry should be returned.
Without the fix, the upcoming dma debug interfaces ("dma-debug: new
interfaces to debug dma mapping errors") can't work reliably because
only device and dma_addr are passed to dma_mapping_error().
