Subject: [PATCH 1/3] ALSA: ens1370: Adjust 15 function calls together with a
variable assignment
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 14 Nov 2017 18:08:57 +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.
