Subject: [PATCH] drm/amd/display: remove an unnecessary NULL check
Date: Mon, 6 Mar 2023 11:28:24 +0000 [thread overview]
Message-ID: <20230306112824.8049-1-listdansp@mail.ru> (raw)
The 'pipe' can't be NULL because it points to an element of array.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
Fixed: 7cf2c840c6b5 (drm/amd/display: Commit validation set from state)
Signed-off-by: Danila Chernetsov <listdansp@mail.ru>
