From bece9e957cbfb37f12488b24166364307e39f5b0 Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 8 Jan 2014 10:40:18 +0000 Subject: ASoC: utils: Add internal call to determine if DAI is dummy. Provide a quick way to tell if a DAI is a dummy DAI or a regular DAI. This is for internal DAPM usage only and is used to determine whether to insert a DAI link connection into the DAPM graph.
