On 2.6.29 I do not have to set the DMA_PRIVATE flag for
dma_request_channel() to work now. So I guess this patch could be
skipped.
I am quite sure I did the previous testing without any of the DMA
clients enabled. My original work was based on 2.6.29-rc3 IIRC. So I do
not really know why this was needed.
