    Subject[PATCH v5 09/16] rpmsg: smd: add sendto and trysendto ops
    Date
    Implement the sendto ops to support the future rpmsg_char update for the
    vitio backend support.
    The use of sendto in rpmsg_char is needed as a destination address is
    requested at least by the virtio backend.
    The SMD implementation does not need a destination address so ignores it.
