Touchscreen mirror response

Hello,

i replaced my touchscreen with a replacement from china.
Now the x axis is fliped. (I touch top left and my phone reacts on bottom left)

I read of some guys who hacked the kernel driver.
But i need help to find the line in my driver.
Could somebody help me pls?

The driver is possibly one of these:

https://github.com/piccolo-dev/andro...atmel_mxt_ts.c
https://github.com/piccolo-dev/andro...atmel_mxt_ts.c
https://github.com/piccolo-dev/andro..._maxtouch_ts.c

The chip is an Atmel mxt336t.

Thank you very much!!!
