Subject: [PATCH 07/10] drm/edid: Clear the old cea_rev when there's no CEA extension in the new EDID
Date: Wed, 28 Sep 2016 16:51:40 +0300 [thread overview]
Message-ID: <1475070703-6435-8-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1475070703-6435-1-git-send-email-ville.syrjala@linux.intel.com>
From: Ville Syrjälä <ville.syrjala@linux.intel.com>
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.
