From: Roderick Colenbrander <roderick.colenbrander@xxxxxxxx> Hi, Some weeks ago we submitted an earlier version of this patch set, which attempted to blacklist dualshock 3 / 4 motion sensor devices from joydev. The motion sensor devices got picked up since the hid-sony driver in recent months split the motion sensors of in separate devices. The earlier version of this patch set, added a filter to joydev to ignore devices which have INPUT_PROP_ACCELEROMETER set. Dmitry pointed out that often you could use a motion sensor device as a joystick. He felt the issue is with composite devices. The discussion didn't result in a conclusion. This patch set only filters out motion sensors if they are part of a composite device. Since there is no way during driver initialization to determine whether we are dealing with a composite device, we introduce a new property INPUT_PROP_COMPOSITE to determine this. I think having such flag is beneficial for userspace as well, since applications now get a hint that a device is part of a composite device without having to infer this from a EVIOCGPHYS / EVIOCGUINIQ match across devices. Hopefully this patches will be accepted for 4.14, but maybe earlier if still possible as the next wave of distributions will likely be on 4.13 with more users dealing with this issue.
