Subject[PATCH] ASoC: audio-graph-scu-card: Use common error handling code in asoc_graph_card_parse_of()
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sun, 19 Nov 2017 08:51:41 +0100

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.
