I forgot about the change in protocol aspect of this. We still need
documentation stating that when BTN_TOOL_*TAP > max mt slots, the
BTN_TOOL_*TAP events should be used to get the current number of active
touches instead of the number of open MT slots. Would you be able to
send a separate patch for that?

(I'm trying to coerce you into updating the docs partly because you're
touching this area and partly because I'm a bit weary of writing input
protocol docs myself :).

Thanks!
