[PATCH 4.6 19/31] usb: quirks: Add no-lpm quirk for Acer C120 LED Projector

From: Greg Kroah-Hartman
Date: Wed Jul 06 2016 - 21:33:48 EST


4.6-stable review patch. If anyone has any objections, please let me know.

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

From: Hans de Goede <hdegoede@xxxxxxxxxx>

commit 32cb0b37098f4beeff5ad9e325f11b42a6ede56c upstream.

The Acer C120 LED Projector is a USB-3 connected pico projector which
takes both its power and video data from USB-3.

In combination with some hubs this device does not play well with
lpm, so disable lpm for it.
