This is a known issue you are seeing here manifesting itself. Given this
specific error message.

Sorry you are having issues with this!
When you have a moment, consider changes from the following series:
https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git/log/?h=sysfs
Test, and let us know if this fixes the problem for you.
I would appreciate if you could test this for us.
> Do you know what could be causing the duplicate file here?
The series cover letter has a bit of information about what is going on
here, and why, see:
https://lore.kernel.org/linux-pci/20260508043543.217179-1-kwilczynski@kernel.org/#t
Hope this helps.
Thank you!
Krzysztof
