Subject: [PATCH 2/6] ALSA: pcm: Adjust nine function calls together with a variable assignment
Date: Wed, 23 Aug 2017 08:24:34 +0000 [thread overview]
Message-ID: <9fcdbe5a-b17a-dfb8-f4af-a1261da93a38@users.sourceforge.net> (raw)
In-Reply-To: <800d7aa6-d8f2-cbf5-caaa-7e4006976e68@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 23 Aug 2017 09:20:29 +0200
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.
