Subject: [PATCH 1/3] ALSA: korg1212: Adjust eight function calls together with a variable assignment
Date: Thu, 16 Nov 2017 12:51:27 +0100 [thread overview]
Message-ID: <029bd28a-1691-58d8-e1e8-56ae4f189439@users.sourceforge.net> (raw)
In-Reply-To: <3f68211d-51f0-2990-d711-44eaeb85ba4d@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Thu, 16 Nov 2017 09:42:45 +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.
