    Subject[PATCH 04/21] ARM: topology: remove unneeded check for /cpus node
    Date
    Checking for "/cpus" node is not necessary as of_get_cpu_node() will fail
    later on anyways. The call to of_find_node_by_path() also leaks a
    reference. So just remove the check.

    Please ack and I will take via the DT tree. This is dependent on the
    first 2 patches.
