From 15f080f08d48af9388142e45a247c8410736178b Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Fri, 17 Feb 2017 17:20:53 +0200 Subject: [PATCH] drm/edid: respect connector force for drm_get_edid ddc probe MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Skip DDC probe for forced connector status. Don't try to read the EDID if the connector is forced off. Skipping probe for forced on connectors will make more sense when drm_do_get_edid() will handle override and firmware EDIDs.
