Touchscreen driver tslib

There is a patch for tslib. It should be used if during the calibration and the touch event the
message 'tslib: Unknown event type' occurs.
The patch 'tslib-1.0-fix-unkn-event-type.patch' can be found at: "http://github.com/caytchen/buildroot-grasshopper/tree/master/package/tslib/".
How to patch in Buildroot:
1) Put it in your /package/tslib/ directory.
2) Delete in output/build tslib and all packages which linked to tslib and build new.
3) If errors during compilation occurs, input the full path to the file for patching, for example
'./buildroot-2010.08/output/build/tslib-1.0/plugins/input-raw.c'.

Thanks for this information. Does this mean this patch is needed on the PicoMOD6? Then I'll include it for the next release V1.1.

Thank you for your fast response.
I don't know if this is an important patch for tslib.
I have tested tslib without this patch and it works properly.
The only thing that I have noticed is that the message 'Unknown event type ...' no more appears with this patch.
Hope this is useful for you.
Best regards
