Subject: [PATCH 5.4 01/13] Revert "drm/amd/display: Fix memory leaks in S3 resume"
Date: Thu,  7 Jan 2021 15:33:20 +0100	[thread overview]
Message-ID: <20210107143050.100326268@linuxfoundation.org> (raw)
In-Reply-To: <20210107143049.929352526@linuxfoundation.org>

From: Alex Deucher <alexdeucher@gmail.com>

This reverts commit a135a1b4c4db1f3b8cbed9676a40ede39feb3362.

This leads to blank screens on some boards after replugging a
display.  Revert until we understand the root cause and can
fix both the leak and the blank screen after replug.
