[PATCH] input: Fix wrong dimensions check for synaptics

From: Takashi Iwai
Date: Wed Jul 14 2010 - 11:27:40 EST


The commit 83ba9ea8a04b72dfee2515428c15e7414ba4fc61 ommitted the return
line for the old synaptics model accidentally. This resulted in a wrong
check, namely, the dimensions are checked for the old devices that don't
support the query properly.

This patch adds the return line back.
