I forgot to write that those patches have been tested with a Renesas Salvator-X
board (r8a7796/M3-W) and a Renesas Lager board (r8a7790/H2). A more
detailed test description can be found here:
http://elinux.org/Tests:I2C-core-DMA
And sorry for the doubled Signed-offs below the patches. My mistake
here, there should be only the ones from sang-engineering.com.
