Not exactly.

drivers/of/fdt.c:of_fdt_unflatten_tree() is not marked __init but does
pass kernel_tree_alloc in as a callback to __unflatten_device_tree()

So I don't think we can't just mark kernel_tree_alloc as __init to fix
this problem.

of_fdt_unflatten_tree() seems to be invokable at arbitrary points in
time, even long after we boot up, so I think we'll end up having to
unravel things to other way, removing the __init tag from the various
implementations of prom_early_alloc().
