It turns out this patch breaks probing for the built-in case [1]. As a
result, imx-drm probing is broken in v4.6. I have sent a patch [2] to
fix the issue by matching the crtc components not against dev->of_node
but against an of_node pointer stored in platform data.

Could we apply that or revert commit 407c9eba7897 ("drm/imx: Remove
of_node assignment from ipuv3-crtc driver probe") for the time being?

Either way, applying this patch without doing either of the two will
break imx-drm probing in v4.4 and v4.5 stable, too.
