If anyone has any objections, please let me know. ------------------ From: Alex Deucher 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.
