From: Antonio Ospite <ospite@xxxxxxxxxxxxxxxxx> This fixes the case when a non-multitouch device happens to have a HID code equal to ABS_MT_SLOT, like the Sony Sixaxis has for the left dpad analog control. Updated to latest tree by Benjamin Tissoires. Signed-off-by: Benjamin Tissoires <benjamin.tissoires@xxxxxxxxxx> --- This patch was sent back in 2011 by Antonio and it was forgotten in the depth of the LKML: http://www.spinics.net/lists/linux-input/msg16881.html Resurecting it now, as the bug is still there. Antonio, could you please tell me if you still add your Signed-of-by line and if I can keep your from?
