From b3bba9a1a8dfcd338eb7d099dcd53daacb698f8b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 8 May 2012 10:33:47 +0100 Subject: [PATCH] ASoC: pcm: Fix DPCM for aux_devs When we instantiate an aux_dev we use a fake rtd as part of the process which doesn't have a dai_link associated with it. Fix the dpcm startup code to cope with this.
