[PATCH 1/2] ALSA: us122l: Use common error handling code in us122l_create_card()

Show all headers | View raw

From: Markus Elfring <elfring@users.sourceforge.net>
Date: Wed, 6 Sep 2017 14:45:09 +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.
