Ok, I did some more testing, and found out rather bogus values in

Input device name: "TSC2005 touchscreen"
Supported events:
Event type 0 (EV_SYN)
Event type 1 (EV_KEY)
Event code 330 (BTN_TOUCH)
Event type 3 (EV_ABS)
Event code 0 (ABS_X)
Value 2514
Min 0
Max 0
Fuzz 4

Which made me go through the git logs, and these patches looked
suspicious. After a revert... yes, touchscreen works as well as it
worked before.


(It is impossible to revert just 3eea..)

Its funny... changelog complains about duplicated code.. then inserts
30 lines of code. Along with check that was not there before.

Maxime, can you suggest a fix?
(cesky, pictures)
