Subject[PATCH 1/2] drm/tegra: Use common error handling code in tegra_output_probe()
From
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Tue, 24 Oct 2017 19:12:09 +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.
