Subject: Input: synaptics - fix wrong dimensions check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=bbddd199995ff55f1bb0336cadff4ee3d02b5a2c;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

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.
