From 7c9aa0157ef4b4cc28c98b08a971dc8344e64aab Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Mon, 18 Dec 2017 10:30:12 -0200 Subject: scripts: kernel-doc: replace tabs by spaces Sphinx has a hard time dealing with tabs, causing it to misinterpret paragraph continuation. As we're now mainly focused on supporting ReST output, replace tabs by spaces, in order to avoid troubles when the output is parsed by Sphinx.
