I don't thi
Add some helpers to share the constraints of devices while attaching
to the dmabuf buffer.
At each attach, the constraints are calculated based on the following:
- dma_mask, coherent_dma_mask from struct device,
- max_segment_size, max_segment_count, segment_boundary_mask from
device_dma_parame
