[PATCH 2/3] drm/exynos/gem: Use common error handling code in exynos_drm_gem_init()

[SF Markus Elfring <elfring@users.sourceforge.net>]

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 24 Oct 2017 09:50:54 +0200

Adjust jump targets so that a bit of exception handling can be better
reused at the end of this function.

This issue was detected by using the Coccinelle software.
