Subject: [PATCH][next] drm/amd/display: remove redundant initialization of variable status
Date: Wed, 3 Mar 2021 14:06:54 +0000 [thread overview]
Message-ID: <20210303140654.67950-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The variable status 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>
