[PATCH v2 7/9] ACPI-video: Delete an unnecessary initialisation in three functions

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 9 Aug 2017 15:55:35 +0200

Three local variables will be set to appropriate values a bit later.
Thus omit the explicit initialisation at the beginning of these functions.
