[PATCH] drm/exynos: remove explicit encoder/connector de-initialization

[Andrzej Hajda]

All KMS objects are destroyed by drm_mode_config_cleanup in proper order
so component drivers should not care about it.

Hi Inki,

This is another spin-off of exynos_drm tests regarding your
component support update.
The patch is based as usual on the latest exynos-drm-next branch.

Regards
Andrzej
