I'll update drm_prime_sg_to_page_addr_arrays to support both the current logic
and dma mapped logic and get a patch up this evening.
That way at least nothing else get broke

In that case getting lengths from dma_map_sg would probably cause other issues

It's likely other drivers that rely on these helpers would be similarly broken.
