The patch titled dma-mapping: update the old macro DMA_nBIT_MASK related documentations has been removed from the -mm tree. Its filename was update-the-old-macro-dma_nbit_mask-related-documentations.patch This patch was dropped because it was merged into mainline or a subsystem tree The current -mm tree may be found at http://userweb.kernel.org/~akpm/mmotm/ ------------------------------------------------------ Subject: dma-mapping: update the old macro DMA_nBIT_MASK related documentations From: Yang Hongyang <yanghy@xxxxxxxxxxxxxx> Update the old macro DMA_nBIT_MASK related documentations Signed-off-by: Yang Hongyang<yanghy@xxxxxxxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- Documentation/DMA-mapping.txt | 18 ++++++------ Documentation/DocBook/writing-an-alsa-driver.tmpl | 8 ++--- 2 files changed, 13 insertions(+), 13 deletions(-) diff -puN Documentation/DMA-mapping.txt~update-the-old-macro-dma_nbit_mask-related-documentations Documentation/DMA-mapping.txt --- a/Documentation/DMA-mapping.txt~update-the-old-macro-dma_nbit_mask-related-documentations +++ a/Documentation/DMA-mapping.txt @@ -136,7 +136,7 @@ exactly why.
