This commit is not applicable for stable kernels and results in the driver failing to load on some chips on kernel 6.16.x. Revert from 6.16.x.

What is special about 6.16.y that causes this to fail, but yet it works in 6.17-rc?
Nothing. It's broken on 6.17-rc as well, but there is already a fix lined up for it for this week. However, this patch was never meant to be applied to stable in the first place. Sasha's tools just auto nominated it. It was part of a rework for new functionality that was added in 6.17. Now the fix patch for 6.17-rc may also fix this for older kernels, but I don't want to risk further regressions in stable.
