The device node iterators perform an of_node_get on each iteration, so a jump out of the loop requires an of_node_put. The patches for drivers/gpu/drm/imx/imx-ldb.c and drivers/gpu/drm/sun4i/sun4i_backend.c contain some added of_node_puts for which the need was identified manually. Details are in the patch logs. --- drivers/gpu/drm/imx/imx-ldb.c | 25 +++++++++++++++++-------- drivers/gpu/drm/mediatek/mtk_drm_drv.c | 5 ++++- drivers/gpu/drm/rockchip/rockchip_rgb.c | 4 +++- drivers/gpu/drm/sun4i/sun4i_backend.c | 1 + 4 files changed, 25 insertions(+), 10 deletions(-)
