Subject: [RFC v3 02/10] drm/nouveau/kms: Don't probe eDP connectors more then once
Date: Fri, 5 Feb 2021 18:45:06 -0500 [thread overview]
Message-ID: <20210205234515.1216538-3-lyude@redhat.com> (raw)
In-Reply-To: <20210205234515.1216538-1-lyude@redhat.com>
eDP doesn't do hotplugging, so there's no reason for us to reprobe it (unless a
connection status change is being forced, of course).
