From e043046a5a29bebe7e9a68b92c4580e2888f8ed3 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Fri, 11 Dec 2015 12:27:53 +0100 Subject: s390-ctcm: Delete unnecessary checks before the function call "channel_remove" The channel_remove() function tests whether its argument is NULL and then returns immediately. Thus the test around the calls is not needed. This issue was detected by using the Coccinelle software. Signed-off-by: Markus Elfring Signed-off-by: Ursula Braun Signed-off-by: David S.
