[PATCH 2/2] ALSA: usx2y: Use common error handling code in submit_urbs()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 6 Sep 2017 15:00:08 +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.
