so, Yes, this is not my blocking patch that prevents me from sending
the new patchset. I intend to let you clean this up with your new
patch.
The v3 is on it's way!

yes, maybe, but at the beginning, we didn't want to patch it that way
because it was only specific to one hid-multitouch device (though
armless for the other multitouch devices).
So maybe you will have to add a quirk in usbhid or sth like that.

Cheers,
Benjamin
