[PATCH] gpu: do not double put device node in zx_drm_probe

for_each_available_child_of_node will get and put the node properly, the following of_node_put will lead to the double put. So just remove it. Signed-off-by: zhong jiang --- drivers/gpu/drm/zte/zx_drm_drv.c | 4 +--- 1 file changed, 1 insertion(+), 3 deletions(-) diff --git a/drivers/gpu/drm
