From b7deac31979bd09c69e0e6e064609fad55df35be Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Wed, 21 Aug 2019 21:48:46 +0200 Subject: [PATCH] =?UTF-8?q?hamradio:=20Delete=20unnecessary=20checks=20bef?= =?UTF-8?q?ore=20the=20macro=20call=20=E2=80=9Cdev=5Fkfree=5Fskb=E2=80=9D?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 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. Signed-off-by: Markus Elfring Signed-off-by: David S.
