spi: spi-davinci: Fix direction in dma_map_single()

The following patch I already sent on 2013-04-18 and 2013-06-06. Unfortunately it hasn't been committed yet.

Commit 048177ce3b3962852fd34a7e04938959271c7e70 (spi: spi-davinci:
convert to DMA engine API) introduced a regression: dma_map_single() is called with direction DMA_FROM_DEVICE for rx and for tx.

I'm not sure where you submitted this to but it doesn't appear to have been to either me or to the mailing list. If you want a patch applying you need to send it to the maintainer as covered in SubmittingPatches. Google and your current post suggest it went to lkml and the retired sourceforge list...

As also covered in SubmittingPatches you should also not include things like this in the body of the commit message, put them after the --- where they will be stripped automatically by tools like git am.

This doesn't apply automatically since:
