Subject: [for-next][PATCH 06/11] tracing: Remove redundant initialization of variable ret
Date: Wed, 09 Jun 2021 21:01:36 -0400 [thread overview]
Message-ID: <20210610010157.748531137@goodmis.org> (raw)
In-Reply-To: 20210610010130.069460694@goodmis.org
From: Colin Ian King <colin.king@canonical.com>
The variable ret is being initialized with a value that is never read,
it is being updated later on. The assignment is redundant and can be
removed.
