Subject[ 058/123] Input: sentelic - only report position of first finger as ST coordinates
Date
3.7-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe TORDEUX <christophe@tordeux.net>

commit a25461659050b913e114d282bf58823682eb56b6 upstream.

Report only the position of the first finger as absolute non-MT coordinates,
instead of reporting both fingers alternatively. Actual MT events are
unaffected.

This fixes horizontal and improves vertical scrolling with the touchpad.
