scripts: get_abi.pl: Don't let ABI files to create subtitles
The ReST output should only contain documentation titles automatically created by the script. There are two reasons for that: 1) Consistency. just a handful ABI docs define titles 2) To avoid critical errors. Docutils (which is the basis for Sphinx) allows a free assign of documentation title markups. So, one document could be doing things like: Level 1 ======= Level 2 ------- While another one could do the reverse: Level 1 ------- Level 2 ======= But the same document can't mix. As the output of get_abi.pl will join contents from multiple files, if they don't define the levels on a consistent errors, errors like this can happen: Sphinx parallel build error: docutils.utils.SystemMessage: /home/rdunlap/lnx/lnx-510-rc2/Documentation/ABI/testing/sysfs-bus-rapidio:2: (SEVERE/4) Title level inconsistent: Attributes Common for All RapidIO Devices ----------------------------------------- Which cause some versions of Sphinx to go into an endless loop. It should be noticed that an alternative to that would be to replace all title occurrences by a single markup, but that will make the parser more complex, and, due to (1) it would generate an inconsistent output. So, better to just remove the titles defined at the ABI files from the output.
