The tree returned from of_fdt_unflatten_tree cannot be attached to the
live tree because it is not marked as detached so mark it as such. The

Hello,
it seems that const pointers to devicetree property content are often

Saving pointers into static devicetree should be fine but saving
pointers into an overlay that can be destroyed is somewhat
problematic.
Typically the property would be used by a driver that
