Hi,

I am intending to queue up this change for v3.13.

I am wondering if you could give me some details of dependencies
of this change on the previous patch. If possible I would
like to apply this patch in a branch that does not include the previous patch.

Also, could you provide a patch to update the marzen defconfig?

Lastly, the driver does not seem to compile as it makes use of
shdma_free_irq() which was removed by Guennadi in
c1c63a14f4f2419d ("DMA: shdma: switch to managed resource allocation").
