Subject: [PATCH 24/40] drm/amd/display: Guard against NULL link encoder in log hw state
Date: Thu, 30 Jun 2022 15:13:06 -0400 [thread overview]
Message-ID: <20220630191322.909650-25-Rodrigo.Siqueira@amd.com> (raw)
In-Reply-To: <20220630191322.909650-1-Rodrigo.Siqueira@amd.com>
From: Nicholas Kazlauskas <nicholas.kazlauskas@amd.com>
[Why & How]
Check lenc is not NULL since dynamic link encoder assignment could
end up assigning a NULL link encoder.
