After scratching my head for a while, I found that the issue was missing empty lines before three different code-block sections.
The line number is definitely bogus, but I wasn't able to discover why.

You can find my patch at: https://lkml.org/lkml/2020/11/30/1196
The patch depends on the v2 patch set Mike Travis <mike.travis@....com> submitted, which hasn't made it to tip yet.

Thanks,
-Justin
