Subject[PATCH] ALSA: cs5530: Use common error handling code in snd_cs5530_probe()
Date
From: Markus Elfring <elfring@users.sourceforge.net>
Date: Sat, 18 Nov 2017 22:10:19 +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.
