From 6f39ed4f0939e6bef722f0096894c1a986da9c9a Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 5 Sep 2017 14:10:15 +0200 Subject: [PATCH] drm/bridge: adv7511: Properly update EDID when no EDID was found Currently adv7511_get_modes() bails out early when no EDID could be retrieved. This leaves the previous EDID in place, which is typically not the intended behavior and might confuse applications. Instead the EDID should be cleared when no EDID could be retrieved. All functions that are called after the EDID check handle the case where the EDID is NULL just fine and exhibit the expected behavior, so just drop the check.
