I'm a bit nervous about the fact that currently both the pen down IRQ
and the coordinate read are pushed through a single workqueue so are
serialised but after your patch they'll be split into the IRQ thread and
the workqueue.  It *should* be fine but I'd have to sit there and study
it to convince myself that it's safe.
