(cherry picked from commit 0e69ef6ea82e8eece7d2b2b45a0da9670eaaefff)
This was CC to stable, but failed to apply because the file was
renamed in 6.3-rc1 as part of
54618888d1ea ("drm/amd/display: break down dc_link.c")

It also is not in 6.4.y, why not?  I can't take it for 6.1.y only,
otherwise people will have a regression when they move to a new kernel.

thanks,

This is one of those cases that the same commit landed in the tree twice as two hashes.

Here's the 6.4 hash (which is identical):

$ git describe --contains 7c5835bcb9176df94683396f1c0e5df6bf5094b3
v6.4-rc7~9^2~2^2
