[PATCH 4.19 43/73] docs: Fix conf.py for Sphinx 2.0

[Greg Kroah-Hartman]

From: Jonathan Corbet <corbet@xxxxxxx>

commit 3bc8088464712fdcb078eefb68837ccfcc413c88 upstream.

Our version check in Documentation/conf.py never envisioned a world where
Sphinx moved beyond 1.x.  Now that the unthinkable has happened, fix our
version check to handle higher version numbers correctly.
