Unreadable thunderbolt nvm_version under sysfs

[AceLan Kao]

[Impact]
Upgrading the TBT firmware through fwupdmgr and encounter the error.
It was working well with 6.8 kernel.

ubuntu@localhost:~$ sudo fwupdtool get-updates

[Fix]

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.

This bug is awaiting verification that the linux-oem-6.11/6.11.0-1008.8 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-done-noble-linux-oem-6.11'. If the problem still exists, change the tag 'verification-needed-noble-linux-oem-6.11' to 'verification-failed-noble-linux-oem-6.11'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

Ubuntu 24.10 (Oracular Oriole) has reached end of life, so this bug will not be fixed for that specific release.
