Hi Marek,
Thank you for the patch.

If device has no DMA max_seg_size set, we assume that there is no limit
and it is safe to force it to use DMA_BIT_MASK(32) as max_seg_size to
let DMA-mapping API always create contiguous mappings in DMA address
space. This is essential for all devices, which use dma-contig
