So, I applied this.  But I had to make an extra amend step to
fix three things after applying it:

    - Remove the meta-comment, (placed after triple dash line)
    - Remove the extraneous "(v2)", (placed in Subject brackets)
    - Remove the duplicate Subject: line, (not repeated in body)

If instead the patch were formatted thusly, it would all just work:

    To: David Gibson <david at gibson.dropbear.id.au>

    Subject: [PATCH v2] dtc: Allow multiple labels on nodes and properties

    At present, both the grammar and our internal data structures mean
    that there can be only one label on a node or property.  This is a
    fairly arbitrary constraint, given that any number of value labels can
    appear at the same point, and that in C you can have any number of
    labels on the same statement.
    
    This is pretty much a non-issue now, but it may become important with
    some of the extensions that Grant and I have in mind.  It's not that
    hard to change, so this patch does so, allowing an arbitrary number of
    labels on any given node or property.  As usual a testcase is added
    too.

    Oops, don't apply that one, it has an uninitialized variable bug.
    Here's a fixed version.
