I'm sorry for the latency, I was off-the-grid in the past weeks.

I observed that warnings in an earlier revision of the relevant patch,
but I thought the previous commit:

eade9f57ca72 ("scripts/kernel_doc.py: properly handle
VIRTIO_DECLARE_FEATURES")

addressed it. At least I can't see the warnings locally while running:

make V=1 C=1 htmldocs

Perhaps it's sphinx version dependent? I'm using sphinx-build 7.3.7
Could you please share the exact command line and tools version used?

Thanks,

Paolo
