6.17-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alex Deucher alexander.deucher@amd.com

commit 3126c9ccb4373d8758733c6699ba5ab93dbe5c9d upstream.

This reverts commit 2681bf4ae8d24df950138b8c9ea9c271cd62e414.

This results in a blank screen on the HDMI port on some systems. Revert for now so as not to regress 6.18, can be addressed in 6.19 once the issue is root caused.
