[Impact]
Monitors black out when an external one connects via thunderbolt3 on AMD Ryzen
9 PRO 7940HS w/ Radeon 780M Graphics.
[Fix]
This can be fixed by upstream linux-firmware commit 253cc179d849 ("amdgpu:
Update DMCUB for DCN314 & Yellow Carp").
However, in linux-firmware/lunar and jammy, the commit history related to the
files to be updated often associated with many other more, they're now updated
with overwrites without cherry-pick ancestor commits along the history.
For linux-firmware/mantic, a simple cherry-pick would do.
[Test Case]
Connect an tbt3 featured external monitor (ASUS PA27AC) after boot to GUI.
Check if both the built-in and external monitors lights up as usual.
[Where problems could occur]
Update amdgpu firmware are error prone, verified on targeting series as
possible.
[Other Info]
While this affects linux-oem-6.1/jammy, as well as linux/lunar kernels, Jammy
and Lunar are nominated for fix.
