Subject: [PATCH 3/3] serial: ioc3: Adjust two function calls together with a
 variable assignment

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 9 Dec 2017 18:48:57 +0100

The script "checkpatch.pl" pointed information out like the following.

ERROR: do not use assignment in if condition

Thus fix the affected source code places.
