Mika helps to fix the issue
https://patchwork.kernel.org/project/linux-usb/patch/20241028105121.894978-1-mika.westerb...@linux.intel.com/
The issue is introduced by below commit in v6.11-rc1, so 6.8 is not affected.
ff6ab055e070 thunderbolt: Add receiver lane margining support for retimers
[Test]
Plug TBT dock and run `sudo fwupdtool get-updates`, there should be no
"failed to read NVM" error.
[Where problems could occur]
The retimer node should not be exposed to the system, the patch fixes the max
index to elimite the nodes. It should be safe and not seems to introduce
regressions.
