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. The third of patch adds a of_graph_get_port_by_id function to retrieve a port by its known port id from the device tree. Finally, the last three patches convert functions in drm_of.c and imx-drm-core.c to use the for_each_endpoint_of_node macro instead of of_graph_get_next_endpoint. Changes since v2: - Fixed and simplified of_graph_get_port_by_id function - More acks The previous version can be found here: https://lkml.org/lkml/2014/9/10/252 regards Philipp Philipp Zabel (8): [media] soc_camera: Do not decrement endpoint node refcount in the loop imx-drm: Do not decrement endpoint node refcount in the loop of: Decrement refcount of previous endpoint in of_graph_get_next_endpoint of: Add for_each_endpoint_of_node helper macro of: Add of_graph_get_port_by_id function drm: use for_each_endpoint_of_node macro in drm_of_find_possible_crtcs imx-drm: use for_each_endpoint_of_node macro in imx_drm_encoder_get_mux_id imx-drm: use for_each_endpoint_of_node macro in imx_drm_encoder_parse_of drivers/gpu/drm/drm_of.c | 8 ++---- drivers/media/platform/soc_camera/soc_camera.c | 2 +- drivers/of/base.c | 35 ++++++++++++++++++++------ drivers/staging/imx-drm/imx-drm-core.c | 34 ++++++++----------------- include/linux/of_graph.h | 18 +++++++++++++ 5 files changed, 58 insertions(+), 39 deletions(-) -- 2.1.0
