Subject: [PATCH 2/2] ALSA: rme9652: Use common error handling code in
 snd_hdspm_probe()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 5 Sep 2017 22:22:21 +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.
