Subject: [for-linus][PATCH 15/15] tracing: Remove a pointless assignment
Date: Tue, 06 Oct 2020 10:35:01 -0400 [thread overview]
Message-ID: <20201006143512.983073039@goodmis.org> (raw)
In-Reply-To: 20201006143446.182666356@goodmis.org
From: Sudip Mukherjee <sudipm.mukherjee@gmail.com>
The variable 'len' has been assigned a value but is not used after that.
So, remove the assignement.
