Martin Oliveira 62af5ca50c ia64/sba_iommu: return error code from sba_map_sg_attrs() ... The .map_sg() op now expects an error code instead of zero on failure. In the case of a dma_mapping_error() return -EIO as the actual cause is opaque here. sba_coalesce_chunks() may only presently fail if sba_alloc_range() fails, which in turn only fails if the iommu is out of mapping resources, hence a -ENOMEM is used in that case.
