Subject: [PATCH 10/21] ACPI-video: Return directly after a failed
 input_allocate_device()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Mon, 5 Sep 2016 15:46:19 +0200

* Return directly after a call of the function "input_allocate_device"
  failed at the beginning.

* Delete the jump label "out" which became unnecessary with
  this refactoring.
