Subject: [PATCH v2 08/11] ALSA: hda - macro to get default config device of pin widgets
Date: Fri,  2 Sep 2016 16:34:57 +0530	[thread overview]
Message-ID: <1472814300-5629-9-git-send-email-subhransu.s.prusty@intel.com> (raw)
In-Reply-To: <1472814300-5629-1-git-send-email-subhransu.s.prusty@intel.com>

In ASoC this easy macro can be used to identify the default
endpoint configuration and create DAPM endpoint widgets.
