There is a need to unmap > that memory with the appropriate unmap function. Be specific, AFIACT the issue is that on dma_ops platforms the map will call ops->map_resource for ATTR_MMIO so we must have the unmap call ops->unmap_resournce Maybe these patches should be swapped then, as adding ATTR_MMIO seems like it created this issue?
