Hi Philipp, Thank you for the patch.
I've submitted a fix for the of_graph_get_next_endpoint() function, but it hasn't been applied yet due to the patch series that contained it needing more work. The patch is available at https://patchwork.linuxtv.org/patch/21946/. I can rebase it on top of this series, but I still wanted to let you know about it in case you would like to integrate it.
