Subject: [PATCH] net: dsa: b53: remove redundant premature assignment to new_pvid
Date: Wed, 27 May 2020 13:01:29 +0100 [thread overview]
Message-ID: <20200527120129.172676-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
Variable new_pvid is being assigned with a value that is never read,
the following if statement updates new_pvid with a new value in both
of the if paths. The assignment is redundant and can be removed.
Addresses-Coverity: ("Unused value")
