Commit 6d29cc7dcf2d ("fdt: Fixup only valid memory banks") ended up
being merged twice, first as:

fdt: Fixup only valid memory banks
Memory banks with address 0 and size 0 are empty and should not be
passed to the OS via device tree.

and later again, though this time it was v2:

The second version was slightly different, so the main hunk of the patch
was applied twice. This isn't harmful because the code is idempotent,
but it's wasteful to run the same code twice.
