<b>Subject:</b> [PATCH] drm/amd/display: avoid printing ERROR for unknown CEA parse(v2)</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">For the unknown CEA parse case on DMUB-enabled ASICs, dmesg will<br>
print an error message like below, this will be captured by<br>
automation tools as it has the word like ERROR during boot up<br>
and treated as a false error, as it does not break bootup process.<br>
So use DRM_WARN printing for this.<br>
<br>
[drm:amdgpu_dm_update_freesync_caps [amdgpu]] *ERROR* Unknown EDID CEA parser results<br>
<br>
v2: Use DRM_WARN to print such info.<br>
