patch "usb: host: xhci-rcar: Add XHCI_TRUST_TX_LENGTH quirk" added to usb-linus

This is a note to let you know that I've just added the patch titled

usb: host: xhci-rcar: Add XHCI_TRUST_TX_LENGTH quirk

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: usb: host: xhci-rcar: Add XHCI_TRUST_TX_LENGTH quirk

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.
