It seems the underlying issue has been solved in
0472bf0 xhci: Prevent U1/U2 link pm states if exit latency is too long

However, the patch to fix the issue when matching the USB_QUIRK_NO_LPM
quirk by iterface could be useful in the future. Currently nothing will
happen that quirk is matched by interface instead of by vid/pid pair.
Is their anything that would need to be changed besides removing the
Description tag?
