Subject: Re: [PATCH] staging: usbip: Fix build on Debian ppc

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?

Regards,
           Tobias Polzer and Dominik Paulus
