    Subject[PATCH v4 08/12] video: da8xx-fb: invoke platform callback safely
    Date
    Ensure that platform data is present before checking whether platform
    callback is present (the one used to control backlight). So far this
    was not an issue as driver was purely non-DT triggered, but now DT
    support has been added.
