Subject: [PATCH 14/22] drm/amd/display: No display after resume from WB/CB[modify]
Date: Fri, 18 Nov 2022 20:59:27 +0800	[thread overview]
Message-ID: <20221118125935.4013669-15-Brian.Chang@amd.com> (raw)
In-Reply-To: <20221118125935.4013669-1-Brian.Chang@amd.com>

From: Tsung-hua Lin <Tsung-hua.Lin@amd.com>

[why]
First MST sideband message returns AUX_RET_ERROR_HPD_DISCON
on certain intel platform. Aux transaction considered failure
if HPD unexpected pulled low. The actual aux transaction success
in such case, hence do not return error.

[how]
Not returning error when AUX_RET_ERROR_HPD_DISCON detected
on the first sideband message.
