v4l2: Includes touch devices in the source list
Created by: ndufresne
Just reporting, this was an ABI break in Linux V4L2, but touch devices ends up being listed as capture devices. Though, their pixel format are not supported. I think it's better to just ignore them from the monitors as it will otherwise confuse usespace looking for a webcam. It's likely only specialized software can handle these streams in order to produce touch events.
