Subject: [PATCH 1/2] ALSA: rme96: Adjust 11 function calls together with a
variable assignment
From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Sat, 18 Nov 2017 13:23:20 +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.
