Subject[PATCH 1/2] ALSA: mixart: Adjust 23 function calls together with a variable assignment
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 16 Nov 2017 15:26:12 +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.
