Subject: [PATCH] ata: ahci-imx: remove redundant assignment to ret
Date: Sun, 5 Apr 2020 12:51:20 +0100 [thread overview]
Message-ID: <20200405115120.366864-1-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")
