Any thoughts on how to fix it?
Make the left side call le32_to_cpu(qh->hw_qtd_next), so that when DMA addresses are 64 bits it still behaves. Real bug, but not many folk should be using that file ... :) Was that all that sparse said? When I've tried it, most options seem to emit so many false positives as to make the output be not very useful. - Dave ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
