Hi Robin,
Thank you for the patch.

Since commit 9495b7e92f71 ("driver core: platform: Initialize dma_parms
for platform devices"), struct platform_device already provides a
dma_parms structure, so we can save allocating another one.
Also the DMA segment size is simply a size, not a bitmask.

Looks good to me, I like the simplification.
Should I get this upstream, or do you have other similar patches
tree-wide that you plan to get merged in one go ?
No, there's no dependency here - I did these as individual per-driver
patches so that they can be applied however, please go ahead :)
Thanks,
Robin.
