[0/2] drm/mediatek: Fix child node refcount handling and use scoped macro

Message

This series fixes a wrong handling of the child node within the
for_each_child_of_node() by adding the missing call to of_node_put() to
make it compatible with stable kernels that don't provide the scoped
variant of the macro, which is more secure and was introduced early this
year.
