From bbddd199995ff55f1bb0336cadff4ee3d02b5a2c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Wed, 14 Jul 2010 09:32:46 -0700 Subject: [PATCH] Input: synaptics - fix wrong dimensions check 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.
