Subject: [PATCH 6/6] GPU-DRM-GMA500: Rename a jump label in mid_get_vbt_data()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 20 Sep 2016 10:40:22 +0200

* Adjust a jump target.

* Delete the explicit initialisation for the local variable "ret"
  which became unnecessary with this refactoring.
