Subject: [PATCH] ttyprintk: remove redundant initialization of variable ret
Date: Thu, 11 Jun 2020 15:31:08 +0000 [thread overview]
Message-ID: <20200611153108.927614-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The variable ret is being initialized with a value that is never read
and it is being updated later with a new value. The initialization is
redundant and can be removed.
Addresses-Coverity: ("Unused value")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
