I was asking Nelson; a symlink with known path and event index in it
will solve it.

Let me simplify the thread by pointing out the kernel side of this is
already implemented for a while and is completely backwards compatible
with tslib and tslib applets by default, so all this talk of destruction
does not apply.

No the kernel touchscreen filter stuff is independent of the driver, it
is implemented separately and resuably.

I agree upstream requirement for tslib seems entrenched, and yet we have
a really good solution for GTA02 touchscreen function in kernel now that
we didn't have before, and couldn't get until now in tslib. And that's
true whether upstream sees value in no-tslib solution or not.
It'll help getting this upstream if it allows complete removal of tslib,
~ so it's good to hear these points, but it's also good Nelson is asking
about what's involved to remove the anomalies created by tslib elsewhere
as part of studying that...
