[alsa-devel] [PATCH] ALSA: cmipci: Use common error handling code in snd_cmipci_probe()

[SF Markus Elfring]

From: Markus Elfring <elfring at users.sourceforge.net>
Date: Tue, 22 Aug 2017 19:58:30 +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.
