    Subject[PATCH v2 6/7] tile/topology: Remove the unused parent_node() macro
    Date
    Commit a7be6e5a7f8d ("mm: drop useless local parameters of
    __register_one_node()") removes the last user of parent_node().

    The parent_node() macro in tile platform is unnecessary.

    Remove it for cleanup.
