Nope, this one is not correct. Please check the arm_iommu_map_sg() function. It calls 
__map_sg_chunk() and gives it &dma->dma_address as one of the arguments, so the dma 
address is correctly stored in the scatter list. Please note that scatterlist is really
non-trivial structure and information about physical memory pages/chunks is disjoint 
from the information about dma address space chunks, although both are stored on the 
same list. In arm_iommu_map_sg() 's' pointer is used for physical memory chunks and 
'dma' pointer is used for dma address space chunks. 

The number of dma address space chunks (returned by arm_iommu_map_sq) can be lower 
than the number of physical memory chunks (given as nents argument).

In case of IOMMU you usually construct the scatter list in such a way, that you get
only one dma address chunk (so in fact you get a buffer mapped contiguously in 
virtual io address space).
