Subject: [PATCH 1/3] ALSA: cs4281: Adjust 18 function calls together with a
variable assignment
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 13 Nov 2017 12:52:53 +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.
