When building htmldocs, the following warnings appear:

Documentation/trace/ftrace.rst:2797: WARNING: Literal block expected; none found.
Documentation/trace/ftrace.rst:2816: WARNING: Literal block expected; none found.

So fix it.

Remember to also Cc linux-trace-kernel@vger.kernel.org

(I pulled it in regardless)

And I also updated the subject to be:

  tracing: Fix warnings when building htmldocs for function graph retval

As it should start with a capital letter, and be more specific than just
general htmldoc fix.
