Hi Liu,

Thanks for the review.

Yes, I agree. I will make the stable fix minimal by not changing the
helper function pattern. In v5, I will only avoid using the cleanup
action for the endpoint node in imx8qxp_pxl2dpi_find_next_bridge() and
release it explicitly with of_node_put() after
of_graph_get_remote_port_parent().

The NULL initialization was only needed because v4 changed the helper
to use an output argument together with a cleanup variable. With the
minimal fix, ep will be a normal pointer, so the NULL initialization
is not needed.

I will send a v5.
