From c44166fe5f38f0559eff1138cca094f3460e2345 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 20 Mar 2020 16:11:02 +0100 Subject: docs: prevent warnings due to autosectionlabel Changeset 58ad30cf91f0 ("docs: fix reference to core-api/namespaces.rst") enabled a new feature at Sphinx: it will now generate index for each document title, plus to each chapter inside it. There's a drawback, though: one document cannot have two sections with the same name anymore. A followup patch will change the logic of autosectionlabel to avoid most creating references for every single section title, but still we need to be able to reference the chapters inside a document. There are a few places where there are two chapters with the same name. This patch renames one of the chapters, in order to avoid symbol conflict within the same document.
