From: Antonio Ospite <redacted>

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.

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?

Cheers,
Benjamin
