Presumably that's because we no longer know what the parent resource

See drivers/gpio/gpio-xilinx.c:

This patch series cleans up the handling of cookies in DMA engine drivers.
This is done by providing a set of inline library functions for common
tasks:
- moving the 'last completed cookie' into struct dma_chan - everyone
has this in their driver private channel data structure
- consolidate
Now that we have the completed cookie in the dma_chan structure, we
can consolidate the tx_status functions by providing a function to set
the txstate structure and returning the DMA status. We also provide
a separate helper to set the residue for cookies which are still in
progress.
Every DMA engine implementation declares a last completed dma cookie
in their private dma channel structures. This is pointless, and
forces driver specific code. Move this out into the common dma_chan
structure.

Everyone deals with assigning DMA cookies in the same way (it's part of
the API so they should be), so lets consolidate the common code into a
helper function to avoid this duplication.
