While this works, "synaptics_i2c" is not a well-formed DT compatible string,
we should do it right.

Please submit three patches:

a) one patch add "syna" as the vendor string in
   Documentation/devicetree/bindings/vendor-prefixes.txt
   As this is a publicly traded company, we use the stock ticker
   symbol by convention. Cc the patch to devicetree at vger.kernel.org
   for review, but I can merge it along with the dts patch if nobody
   else does

b) a patch to add an of_device_id match table to
   drivers/input/mouse/synaptics_i2c.c, with the proper name of the
   device. Ideally, this would be the full name of the component that
   is used here, something like "syna,abc12345-touchscreen". If you
   have no way of finding out the real name, "syna,i2c-touchscreen"
   will have to suffice.

c) This patch, with the correct string used for compatible.
