Subject: [igt-dev] [PATCH i-g-t 4/5] lib/kms: Skip no-op display updates
Date: Fri, 14 Sep 2018 21:13:09 +0100	[thread overview]
Message-ID: <20180914201310.19527-4-chris@chris-wilson.co.uk> (raw)
In-Reply-To: <20180914201310.19527-1-chris@chris-wilson.co.uk>

If the display is disabled (e.g. the driver has disabled the KMS
interface) there is nothing to do so avoid failing.
