From a88b1672d4ddf9895eb53e6980926d5e960dea8e Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 22 Jul 2016 11:46:36 -0300 Subject: [PATCH] doc-rst: kernel-doc: fix handling of address_space tags The RST cpp:function handler is very pedantic: it doesn't allow any macros like __user on it: Documentation/media/kapi/dtv-core.rst:28: WARNING: Error when parsing function declaration. If the function has no return type: Error in declarator or parameters and qualifiers Invalid definition: Expecting "(" in parameters_and_qualifiers.
