Subject: [PATCH 1/2] ALSA: au88x0: Adjust 40 function calls together with a
variable assignment
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sun, 12 Nov 2017 21:48:44 +0100
The script "checkpatch.pl" pointed information out like the following.
ERROR: do not use assignment in if condition
Thus fix affected source code places.
