Another lint alternative: use the lint from the linuxdoc project install the linuxdoc package: * https://return42.github.io/linuxdoc/install.html e.g.:: pip install --user git+http://github.com/return42/linuxdoc.git and run kernel-lintdoc with the file/folder to lint as argument / e.g.:: kernel-lintdoc include/media/ -- Markus -- > > > From 1244efa0f63a7b13795e8c37f81733a3c8bfc56a Mon Sep 17 00:00:00 2001 > From: Jani Nikula > Date: Tue, 31 May 2016 18:11:33 +0300 > Subject: [PATCH] kernel-doc-rst-lint: add tool to check kernel-doc and rst > correctness > Organization: Intel Finland Oy - BIC 0357606-4 - Westendinkatu 7, 02160 Espoo > Cc: Jani Nikula > > Simple kernel-doc and reStructuredText lint tool that can be used > independently and as a kernel build CHECK tool to validate kernel-doc > comments. > > Independent usage: > $ kernel-doc-rst-lint FILE > > Kernel CHECK usage: > $ make CHECK=scripts/kernel-doc-rst-lint C=1 # (or C=2) > > Depends on docutils and the rst-lint package > https://pypi.python.org/pypi/restructuredtext_lint > > Signed-off-by: Jani Nikula > --- > scripts/kernel-doc-rst-lint | 106 ++++++++++++++++++++++++++++++++++++++++++++ > 1 file changed, 106 insertions(+) > create mode 100755 scripts/kernel-doc-rst-lint > > diff --git a/scripts/kernel-doc-rst-lint b/scripts/kernel-doc-rst-lint > new file mode 100755 > index 000000000000..7e0157679f83 > --- /dev/null > +++ b/scripts/kernel-doc-rst-lint > @@ -0,0 +1,106 @@ > +#!/usr/bin/env python > +# coding=utf-8 > +# > +# Copyright ? 2016 Intel Corporation > +# > +# Permission is hereby granted, free of charge, to any person obtaining a > +# copy of this software and associated documentation files (the "Software"), > +# to deal in the Software without restriction, including without limitation > +# the rights to use, copy, modify, merge, publish, distribute, sublicense, > +# and/or sell copies of the Software, and to permit persons to whom the > +# Software is furnished to do so, subject to the following conditions: > +# > +# The above copyright notice and this permission notice (including the next > +# paragraph) shall be included in all copies or substantial portions of the > +# Software. > +# > +# THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR > +# IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, > +# FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
