drm/drm_panel: Fix EXPORT of drm_panel_of_backlight() one more time
The initial commit followed by the fix didn't
take into consideration the case:
CONFIG_DRM_PANEL=y
CONFIG_BACKLIGHT_CLASS_DEVICE=m
CONFIG_DRM_I915=y
where symbol devm_of_find_backlight() is not reachable from DRM subsystem.
Quick fix is to avoid drm_panel_of_backlight() from exporting in such case.
