Subject: [PATCH AUTOSEL for 4.9 138/293] Docs: Fix breakage with Sphinx 1.5
 and upper

From: Mauro Carvalho Chehab <mchehab@...pensource.com>

[ Upstream commit 633d612bda6a37e1d5f5f878ec5a22a11599f800 ]

Commit 85c21e5c3ee7 (docs-rst: better adjust margins and font size) added a
\usepackage{geometry} that conflicts with another inclusion deep within the
dependencies with newer versions of Sphinx, causing the the PDF build to fail
with a "conflicting parameters" error.

Detect the Sphinx version, using sphinxsetup for Sphinx versions 1.5 and
upper.

Fixes: 85c21e5c3ee74fb75d690c57f7066bae7e2dca55
