Subject: [for-linus][PATCH 6/7] ftrace: Remove redundant initialization of variable ret
Date: Fri, 23 Jul 2021 08:55:00 -0400	[thread overview]
Message-ID: <20210723125634.402366446@goodmis.org> (raw)
In-Reply-To: <20210723125454.570472450@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.
