Subject: [PATCH 4.9 65/88] usb: quirks: add NO_LPM quirk for Logitech Screen Share

From: Dan Lazewatsky <dlaz@...omium.org>

commit b96ed52d781a2026d0c0daa5787c6f3d45415862 upstream.

LPM on the device appears to cause xHCI host controllers to claim
that there isn't enough bandwidth to support additional devices.
