[Impact]
There is no output of external 4k DP monitor via USB-C to DP dongle.

Verified on hardware, external 4k monitor works fine after re-plugin and suspend.

[Where problems could occur]
It may break the display output on AMD GPU.

This commit is from 5.18-rc1, and no issue on jammy kernel.
SRU for oem-5.17 only.

This bug is awaiting verification that the linux-oem-5.17/5.17.0-1017.18 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-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

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!

I didn't reproduce this issue on 5.15.
Did anyone reproduce it and can verify it?
If so I can do SRU for it.
