Thanks for this report. So, Sphinx errors are not fun to debug. I took a lot of
fiddling to figure out that Sphinx really had the problem several lines down,
but was considering everything after the "What:" line as a single block staring
at line 38.

By trial and error this change made it happy:

Subject: [PATCH] Documentation/ABI/testing/debugfs-cxl: Fix "Unexpected
 indentation"

Stephen reported that an htmldocs build hit:

   Documentation/ABI/testing/debugfs-cxl:38: ERROR: Unexpected indentation.

It turns out that line was fine but the tool was unhappy about some line
breaks in the table of values to error types.

It turns out that:

   make V=1 SPHINXDIRS="admin-guide" htmldocs

...can not be used to get more info about what is behind a documentation
build error. It was only pure luck that reflowing the text resulted in
an error message that seemed a imply a problem later on with line breaks
around the table.
