Subject: [PATCH] Bluetooth-cmtp: Delete an unnecessary check before the function call "kfree_skb"
Date: Sat, 14 Nov 2015 22:10:22 +0100 [thread overview]
Message-ID: <5647A33E.3030103@users.sourceforge.net> (raw)
In-Reply-To: <5317A59D.4@users.sourceforge.net>
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 14 Nov 2015 22:00:27 +0100
The kfree_skb() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.
