Subject: [PATCH 3.11 63/66] serial: vt8500: add missing braces

3.11-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roel Kluin <roel.kluin@...il.com>

commit d969de8d83401683420638c8107dcfedb2146f37 upstream.

Due to missing braces on an if statement, in presence of a device_node a
port was always assigned -1, regardless of any alias entries in the
device tree. Conversely, if device_node was NULL, an unitialized port
ended up being used.

This patch adds the missing braces, fixing the issues.
