Hi, Since there now is a merge conflict in imx-drm-core, I've rebased the series onto v4.0-rc1. Also a new driver touched by this change appeared, so the first patch now includes a fix for am437x-vfpe, too. I'd be happy to get an ack for that. This series converts all existing users of of_graph_get_next_endpoint that pass a non-NULL prev argument to the function and decrement its refcount themselves to stop doing that. The of_node_put is moved into of_graph_get_next_endpoint instead. This allows to add a for_each_endpoint_of_node helper macro to loop over all endpoints in a device tree node.
