Subject: Rely on SYN-Events when pen is lifted
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=93e00fec86cd21af033aecea3d165b5250558b8f;p=android-x86%2Fexternal-tslib.git

Rely on SYN-Events when pen is lifted

when the input-raw module of tslib relies on SYN-Events, it should not report
a BTN_TOUCH to upper layers before the corresponding EV_SYN was seen.

This prevents seeing two pen up events as described in my posting from
Jan, 14 2009.
