Subject[PATCH v4 14/15] drm/panel-edp: Don't re-read the EDID every time we power off the panel
Date
The simple-panel driver is for panels that are not hot-pluggable at
runtime. Let's keep our cached EDID around until driver unload.

Changes in v4:
- panel-simple-edp => panel-edp

Changes in v3:
- ("Don't re-read the EDID every time") moved to eDP only patch.
