Subject: [PATCH 1/2] ALSA: mixart: Adjust 23 function calls together with a
variable assignment
From: Markus Elfring <elfring@...rs.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.
