Subject: [for-next][PATCH 4/7] tracing: Remove unneeded NULL check
Date: Sun, 26 Jan 2020 14:19:36 -0500	[thread overview]
Message-ID: <20200126192020.939296571@goodmis.org> (raw)
In-Reply-To: 20200126191932.984391723@goodmis.org

From: Dan Carpenter <dan.carpenter@oracle.com>

We checked "iter->trace" earlier so there is no need to check here.
