From 365ff56f08ee4f2b933c13ab4cd950aad1454521 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Tue, 29 Sep 2020 11:18:20 +0200 Subject: docs: kgdb.rst: fix :c:type: usages Which Sphinx 3, :c:type: can't be used anymore for structs, as this should be used only for typedefs. Rely on automarkup.py for struct references. This file has an special case, though: it uses the tag also to point to an array. Let's use, instead, :c:expr: for such purpose, as it should do the right thing. This should fix this warning: ./Documentation/dev-tools/kgdb.rst:875: WARNING: Unparseable C cross-reference: 'kdb_poll_funcs[]' Invalid C declaration: Expected end of definition.
