-Subject: [PATCH] of: configfs: Use of_overlay_fdt_apply API call
-
-The published API to the dynamic overlay application mechanism now
-takes a Flattened Device Tree blob as input so that it can manage the
-lifetime of the unflattened tree. Conveniently, the new API call -
-of_overlay_fdt_apply - is virtually a drop-in replacement for
-create_overlay, which can now be deleted.
