Subject: [PATCH] drm/dp: Remove dead code after return statement
Date: Sun, 6 Jul 2025 16:24:24 +0000 [thread overview]
Message-ID: <20250706162431.15029-1-len.bao@gmx.us> (raw)
Coverity noticed that the code after the return statement in the
"drm_dp_pcon_frl_configure_2" function is never reached. So, it can be
safely removed.
Coverity-id: 1648885
Fixes: af67978ee37e5 ("drm/display: dp: use new DCPD access helpers")
