When testing usbip under powerpc, it (unexpectedly) worked, but only after removing the following lines from vhch_hcd.c: 1004 /* will be removed */ 1005 if (pdev->dev.dma_mask) { 1006 dev_info(&pdev->dev, "vhci_hcd DMA not supported\n"); 1007 return -EINVAL; 1008 } We encountered no problems without those lines. Is it safe to remove this check?
