Subject: usb: quirks: Add no-lpm quirk for Acer C120 LED Projector
From: Hans de Goede <[email protected]>
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.
