Subject: [PATCH][next] drm/amdgpu: remove redundant assignment to pointer 'ring'
Date: Tue, 23 Jul 2019 14:41:20 +0100 [thread overview]
Message-ID: <20190723134120.28441-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The pointer 'ring' is being assigned a value that is never
read, hence the assignment is redundant and can be removed.
Addresses-Coverity: ("Unused value")
Signed-off-by: Colin Ian King <colin.king@canonical.com>
