I have moved the of/dma.c to dma/of-dma.c, can you regenerate this patch and
resend to me

Sorry Vinod, I didn't manage to get this commit from either linux-next tree or
slave-dma tree, and the last commit by you for of/dma.c file is on Jan 7. Did
you have any hints for me to get the latest version dma/of-dma.c?
