Bug Description

[Impact]
After Apply the patches from https://www.spinics.net/lists/intel-gfx/msg248700.html, the TGL platform would have the failure rate(1/20) on outputting the video through WD19TB.

[Fix]
The patch is provided by Imre(https://gitlab.freedesktop.org/drm/intel/-/issues/2801#note_740352).
If there's no lttpr in the link chain, the DRM driver wouldn't configure the transparent mode again.

[Test Case]
1. Connected the WD19TB with the TGL platform and
connected the external monitor on WD19TB with HDMI/Displayport.
2. Don't plug the external monitor on the TGL platform, so there's only one monitor on WD19TB.
3. Cold boot the TGL platform.
4. Check the monitor can be blinked and the video can output to the monitor.

[Where problems could occur]
As per Imre's comment, this may be caused by the dock.
In the future if the WD19TB's firmware is updated, we may encounter the same issue again.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1910211

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
