Subject: [PATCH][next] ttyprintk: remove redundant initialization of variable i
Date: Tue, 18 May 2021 19:21:26 +0100	[thread overview]
Message-ID: <20210518182126.140978-1-colin.king@canonical.com> (raw)

From: Colin Ian King <colin.king@canonical.com>

The variable i is being initialized with a value that is never read,
it is being updated later on.  The assignment is redundant and can be
removed.

Addresses-Coverity: ("Unused value")
