From 011acce2859ad50b7a923cad4a726220b5f24455 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 28 Sep 2016 16:51:40 +0300 Subject: [PATCH] drm/edid: Clear the old cea_rev when there's no CEA extension in the new EDID MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit It's not a good idea to leave stale cea_rev in the drm_display_info. The current EDID might not even have a CEA ext block in which case we'd end up leaving the stale value in place.
