    Subject[PATCH 4.9 47/56] usb: host: xhci-rcar: Add XHCI_TRUST_TX_LENGTH quirk
    Date
    4.9-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Yasushi Asano <yasano@jp.adit-jv.com>

    commit 40fc165304f0faaae78b761f8ee30b5d216b1850 upstream.

    When plugging BUFFALO LUA4-U3-AGT USB3.0 to Gigabit Ethernet LAN
    Adapter, warning messages filled up dmesg.

    [ 101.098287] xhci-hcd ee000000.usb: WARN Successful completion on short TX for slot 1 ep 4: needs XHCI_TRUST_TX_LENGTH quirk?
    [ 101.117463] xhci-hcd ee000000.usb: WARN Successful completion on short TX for slot 1 ep 4: needs XHCI_TRUST_TX_LENGTH quirk?
    [ 101.136513] xhci-hcd ee000000.usb: WARN Successful completion on short TX for slot 1 ep 4: needs XHCI_TRUST_TX_LENGTH quirk?

    Adding the XHCI_TRUST_TX_LENGTH quirk resolves the issue.
