Subject: [PATCH 1/2] ALSA: vx222: Adjust ten function calls together with a
 variable assignment

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 18 Nov 2017 21:10:37 +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.
