Subject: [PATCH 2/8] doc: Cope with the deprecation of AutoReporter
Date: Wed, 22 May 2019 14:50:28 -0600	[thread overview]
Message-ID: <20190522205034.25724-3-corbet@lwn.net> (raw)
In-Reply-To: <20190522205034.25724-1-corbet@lwn.net>

AutoReporter is going away; recent versions of sphinx emit a warning like:

  /stuff/k/git/kernel/Documentation/sphinx/kerneldoc.py:125:
      RemovedInSphinx20Warning: AutodocReporter is now deprecated.
      Use sphinx.util.docutils.switch_source_input() instead.

Make the switch.  But switch_source_input() only showed up in 1.7, so we
have to do ugly version checks to keep things working in older versions.
