From 16a433d8b38720a816736d59a62e705c19e31600 Mon Sep 17 00:00:00 2001 From: Jaroslav Kysela Date: Wed, 22 Jul 2009 16:20:40 +0200 Subject: ALSA: hda-intel: Cleanups for widget connection list handling This patch adds a check to snd_hda_get_connections() routine for presence of AC_WCAP_CONN_LIST. Also, make sure that negative error codes from noted route are handled on all places as errors.
