Subject: [PATCH 2/4] hamradio: Adjust four function calls together with a variable assignment
Date: Tue, 9 May 2017 16:23:20 +0200	[thread overview]
Message-ID: <28005de5-baf6-9db0-7eaa-7ef14d4e7142@users.sourceforge.net> (raw)
In-Reply-To: <4c5c939a-bd55-7b88-8e41-49f5544b7658@users.sourceforge.net>

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 9 May 2017 15:15:16 +0200

The script "checkpatch.pl" pointed information out like the following.

ERROR: do not use assignment in if condition

Thus fix affected source code places.
Improve a size determination.
