[igt-dev] [PATCH i-g-t 1/2] conf.py: add some backward-compatibility bits

[Mauro Carvalho Chehab <mauro.chehab@linux.intel.com>]

From: Mauro Carvalho Chehab <mchehab@kernel.org>

Currently, Sphinx 1.6 fails to build the documentation and produces
an ugly warning.

Add compatibility bits to avoid it.
