Subject: [PATCH 05/21] ACPI-video: Delete an unnecessary initialisation in
 acpi_video_get_levels()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 5 Sep 2016 14:23:55 +0200

The local variable "br" will be set to an appropriate value a bit later.
Thus omit the explicit initialisation at the beginning.
