I don't believe this is appropriate for stable, looks like
a new feature to me.

Most people won't be using this config so the defaults matter. So why 10? 10 fingers?
And where does 64 come from?
I have sent v3 version where number of slots it obtained from the host.
+ if (is_mt)
+ input_mt_init_slots(vi->idev,

Do we need the number in config space maybe? And maybe with a feature
bit so host can find out whether guest supports MT?
I think it is not applicable in v3 which I sent, because number of slots
is commit from the host. So, now host controls whether guest support MT.
