[PATCH] ASoC: cs4270: Use common error handling code in two functions

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 6 Sep 2017 19:09:31 +0200

Add jump targets so that a bit of exception handling can be better reused
at the end of these functions.

This issue was detected by using the Coccinelle software.
