[AMD Public Use] this branch should be ignored by test robots. It's just a public mirror of our packaged driver source code. It contains kernel compatibility and dkms support which is not going upstream.

Hello,
the mentioned branch requires the following commit, but it is already
applied in 5.10 released kernel,
so I really do not know what next step here.
