Subject: [PATCH] drm/nouveau: Remove redundant error check on variable ret
Date: Fri, 2 Jul 2021 13:05:18 +0100 [thread overview]
Message-ID: <20210702120518.17740-1-colin.king@canonical.com> (raw)
From: Colin Ian King <colin.king@canonical.com>
The call to drm_dp_aux_init never returns an error code and there
is no error return being assigned to variable ret. The check for
an error in ret is always false since ret is still zero from the
start of the function so the init error check and error message
is redundant and can be removed.
Addresses-Coverity: ("Logically dead code")
Fixes: fd43ad9d47e7 ("drm/nouveau/kms/nv50-: Move AUX adapter reg to connector late register/early unregister")
