    Subject[PATCH 17/21] ACPI-video: Delete an unnecessary initialisation in acpi_video_init_brightness()
    From
    Date
    From: Markus Elfring <elfring@users.sourceforge.net>
    Date: Mon, 5 Sep 2016 17:20:22 +0200

    The local variable "result" will be assigned with a statement that follows
    it directly. Thus omit the explicit initialisation at the beginning.
