usb: xhci: Add XHCI_TRUST_TX_LENGTH for Renesas uPD720201developerbox/hacking-v4.14
When plugging in a USB webcam I see the following message: xhci_hcd 0000:04:00.0: WARN Successful completion on short TX: needs XHCI_TRUST_TX_LENGTH quirk? handle_tx_event: 913 callbacks suppressed All is quiet again with this patch (and I've done a fair but of soak testing with the camera since).
