[PATCH v2 5/9] ACPI-video: Delete unnecessary if statement in acpi_video_switch_brightness()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 9 Aug 2017 15:43:17 +0200

Move a function call into an else branch for successful function execution.
Omit a duplicate check for the local variable "result" then at the end.
