9a1c801a1a3c ("Fix discarded const qualifiers")
in git://git.kernel.org/pub/scm/utils/dtc/dtc.git
implements a similar change.

But the patch is not applicable:

error: scripts/dtc/fdtput.c: does not exist in index
error: scripts/dtc/meson.build: does not exist in index

The change in fdt_overlay.c is identical.

Best regards
