[PATCH 1/3] drm/exynos/dsi: Use common error handling code in exynos_dsi_enable()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Tue, 24 Oct 2017 09:32:18 +0200

Add a jump target 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.
