Hi,
The patch "4f6d9e38c4d2 ("drm/amd/display: Add polling method to handle
MST reply packet")" was tagged for stable, but it failed to apply to
both 6.4.y and 6.1.y.
The 6.4.y backport is missing a dependency. So to fix this can you
please apply:
87279fdf5ee0 ("drm/amd/display: Clean up errors & warnings in amdgpu_dm.c")
4f6d9e38c4d2 ("drm/amd/display: Add polling method to handle MST reply
packet")
I intend to also send out a proper 6.1.y backport, but it's a lot more
complex due to other driver changes and will come separately.
Thanks,
