You should _always_ run checkpatch before sending patches. It should
have 0 errors.

ERROR: trailing whitespace
#773: FILE: drivers/dma/sirf-dma.c:649:

Also there are bunch of 80char warning, see if you can reduce/eliminate
them without sacrificing the code readability, and looking at them it
seems possible

Also, Please ensure you send patches which compile with ZERO warnings:
drivers/dma/sirf-dma.c: In function 'sirfsoc_dma_probe':
drivers/dma/sirf-dma.c:616: warning: assignment from incompatible pointer type
drivers/dma/sirf-dma.c:617: warning: assignment from incompatible pointer type
which comes from the fact that your prep_interleaved_dma does not have
last argument of flags.
On the second one you have not rebased to patch from Jassi which I
applied after converting direction stuff.
