[PATCH 2/3] ALSA: sonicvibes: Use common error handling code in snd_sonic_probe()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Sat, 18 Nov 2017 16:10:34 +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.
