This is more of question than comment. I am seeing in some places,
such as mtk_dpi_probe(), of_node_put() is called right after
of_drm_find_bridge() whether or not bridge_node is found.
In this case, of_node_put() is done from exynos_dsi_remove() which looks
correct to me.
However, there is the discrepancy. One of these is incorrect perhaps?
When is the right time to call of_node_put()?

Looks good to me.
