Subject: [PATCH 0/3] HID: multitouch: fix a corner case of some Win 8 devices

It looks like the Microsft certification misses one case of released fingers.

The (only) solution we can have against that is to wait for a hundred of ms,
and if no input report comes in, consider that the touches should have been
released. The spec, as I read it, enforces that.

Arek, can you please give a test to this new series?
I managed to find out a way to have the IRQ and the timeout exclusive, and
also added a few optimizations.

Cheers,
Benjamin
