Subject: [PATCH 0/3] drm/mediatek: fixes for ovl_adaptor

The main fix is a possible memory leak on an early exit in the
for_each_child_of_node() loop. That fix has been divided into a patch
that can be backported (a simple of_node_put()), and another one that
uses the scoped variant of the macro, removing the need for any
of_node_put(). That prevents mistakes if new break/return instructions
are added, but the macro might not be available in older kernels.

When at it, an unused header has been dropped.
