[Patch] Fix for so that recent Elantech touchpads are recognized as such

[Matt Walker <matt.g.d.walker@xxxxxxxxx>]

Hello,

Attached is a patch for drivers/input/mouse/elantech.c.  It allows
recent Elantech touchpads to be detected.  I have tested it on the
touchpad that comes with the Acer Aspire S7-392 (released ~August
2013)

I figure it could be backported with little effort and no danger,
since all it does it add one to the number of values that were
previously recognized as valid "firmware version numbers".

Begin Patch:

End Patch

Best,
Matt
