| Subject: drm/panel: simple: Add missing panel_simple_unprepare() calls |
| |
| From: Jonathan Liu <net147@gmail.com> |
| |
| commit f3621a8eb59a913612c8e6e37d81f16b649f8b6c upstream. |
| |
| During panel removal or system shutdown panel_simple_disable() is called |
| which disables the panel backlight but the panel is still powered due to |
| missing calls to panel_simple_unprepare(). |
| |
| Fixes: d02fd93e2cd8 ("drm/panel: simple - Disable panel on shutdown") |
