Subject: [PATCH 17/21] ACPI-video: Delete an unnecessary initialisation in
 acpi_video_init_brightness()

From: Markus Elfring <elfring@...rs.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.
