I see - the cyttsp_xydata struct seems to be the old version,
though. Any particular reason for that? Also, the similarity to the
problem found here, https://lkml.org/lkml/2011/8/25/516, suggests your
16 tracking ids could be mapped directly to slots instead, using the
example code. It ought to reduce the present patch significantly.

Thanks,
Henrik
