    Subject[PATCH v4 2/8] serial: sunzilog: Remove unnecessary volatile keyword
    Date
    From: Thierry Reding <treding@nvidia.com>

    The field annotated with volatile are all accessed through I/O accessors
    so they don't need to be explicitly marked. The accessors will take care
    of it.

    Signed-off-by: Thierry Reding <treding@nvidia.com>
