No need for this. to_omap_dma_chan(foo->vd.tx.chan) will give you the

sDMA in OMAP3630 or newer SoC have support for LinkedList transfer. When
LinkedList or Descriptor load feature is present we can create the
descriptors for each and program sDMA to walk through the list of
descriptors instead of the current way of sDMA stop, sDMA reconfiguration
and sDMA start afte
