Could you please split this patch?

The copyright change should be a patch on its own.
The changes in the coding style without functional changes also.
Then you can do your changes about removing DMA support for SPL.

However, on this topic, I'm not sure this is a wise idea. Maybe the SPL
should be fixed so that it can work with DMA?

Thanks,
Miquèl
