Subject: [PATCH 03/14] drm/amd/display: Revert changes for MPO underflow
Date: Fri, 12 Nov 2021 08:54:27 +0800 [thread overview]
Message-ID: <20211112005438.5505-4-Wayne.Lin@amd.com> (raw)
In-Reply-To: <20211112005438.5505-1-Wayne.Lin@amd.com>
From: Angus Wang <angus.wang@amd.com>
[WHY]
The previous changes for fixing MPO underflow with multiple
display connected caused a regression where the machine runs
into a hang when doing multiple driver pnp with multiple displays
connected
[HOW]
Reverted offending change
