From: Rene van Paassen Date: Mon, 21 May 2007 04:32:17 +0000 (-0400) Subject: Input: aiptek - rework the function key code X-Git-Tag: v2.6.23-rc1~1178 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=1e7b3faed1793e7637a774240ae22541c5ba6ca0;p=linux-2.6-omap-h63xx.git Input: aiptek - rework the function key code Function keys (also called macro keys) code corrected. Using a lastMacro variable to keep track of key currently pressed. This ensures proper resetting when dragging the pen in the drawing area or to another key. Also suppress sending pressure reports when over the macro key area.
