Subject: [PATCH v2 2/3] drm/radeon: be quiet when no SAD block is found
Date: Wed, 4 Sep 2019 11:13:37 +0200 [thread overview]
Message-ID: <20190904111337.77d4cb7c@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.
Inspired by a similar fix to the amdgpu driver in the context of bug
fdo#107825:
