Subject: [PATCH v2 1/3] drm/amd: be quiet when no SAD block is found
Date: Wed, 4 Sep 2019 11:12:48 +0200 [thread overview]
Message-ID: <20190904111248.61dfdd68@endymion> (raw)
In-Reply-To: <20190904111152.266d5176@endymion>
It is fine for displays without audio functionality to not provide
any SAD block in their EDID. Do not log an error in that case,
just return quietly.
This fixes half of bug fdo#107825:
