Subject: serial: vt8500: add missing braces
X-Git-Url: http://git.mmlx.us/?a=commitdiff_plain;h=bfddde1b4056f5b7d0d365606000df3442b82cd0;p=linux-edison.git

serial: vt8500: add missing braces

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.
