From: Lars-Peter Clausen Date: Tue, 5 Sep 2017 12:10:15 +0000 (+0200) Subject: drm/bridge: adv7511: Properly update EDID when no EDID was found X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6f39ed4f0939e6bef722f0096894c1a986da9c9a;p=linux.git 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.
