Subject: [PATCH v6 5/8] drm/panel: sw43408: Remove manual invocation of
 unprepare at remove

From: David Heidelberg <david@...t.cz>

The drm_panel_remove should take care of disable/unprepare. Remove the
manual call from the sw43408_remove function.

Fixes: 069a6c0e94f9 ("drm: panel: Add LG sw43408 panel driver")
