[PATCH v3 15/16] drm/panel-simple-edp: Don't re-read the EDID every time we power off the panel
From: Douglas Anderson <dianders@chromium.org>
Date: 2021-09-01 20:21:59

The simple-panel driver is for panels that are not hot-pluggable at
runtime. Let's keep our cached EDID around until driver unload.
