Subject: [PATCH AUTOSEL 5.8 36/42] drm/amd/display: Revert HDCP disable sequence change
Date: Mon, 31 Aug 2020 11:29:28 -0400	[thread overview]
Message-ID: <20200831152934.1023912-36-sashal@kernel.org> (raw)
In-Reply-To: <20200831152934.1023912-1-sashal@kernel.org>

From: Jaehyun Chung <jaehyun.chung@amd.com>

[ Upstream commit b61f05622ace5b9498ae279cdfd1c9f0c1ce3f75 ]

[Why]
Revert HDCP disable sequence change that blanks stream before
disabling HDCP. PSP and HW teams are currently investigating the
root cause of why HDCP cannot be disabled before stream blank,
which is expected to work without issues.
