Hi,
next try for v3.20. After the merge window we have a few new users of of_graph_get_next_endpoint, could I please get some acks from the respective maintainers for this to go in through Grant's tree?
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.
Changes since v5: - Rebased onto v3.19-rc1 - Added new users of of_graph_get_next_endpoint, coresight and drm/rcar-du. There's also rockchip, but the driver already doesn't decrement the prev node's reference count. - Dropped the "use for_each_endpoint_of_node macro" patches, I'll add the new users and resend them separately.
The previous version can be found here: https://lkml.org/lkml/2014/9/29/529
regards Philipp
