Set the drm_mode_config->normalize_zpos and call the generic
drm_atomic_helper_check() instead of duplicating it within
tegra_atomic_check().
Call tegra_display_hub_atomic_check() after the drm_atomic_helpre_check()
returned without error.

Thierry,
since the v4 series the atomic check of tegra got additional call to
tegra_display_hub_atomic_check().
Based on the code the order, placement of the hub check is not strict, it can
be done as the last step as well.
But if the hub check needs to be called in certain step, then I can drop the
tegra patch.
Can you check if this patch is OK or not?
Regards,
Peter
