Subject: [PATCH net-next] s390/ctcm: Delete unnecessary checks before the macro call “dev_kfree_skb”
Date: Sun, 15 Sep 2019 19:21:05 +0200 [thread overview]
Message-ID: <20190915172105.42024-1-jwi@linux.ibm.com> (raw)
From: Markus Elfring <elfring@users.sourceforge.net>
The dev_kfree_skb() function performs also input parameter validation.
Thus the test around the shown calls is not needed.
This issue was detected by using the Coccinelle software.
