From 8d946dd7dc5cc3f0eae3d6df2c9e927497e38850 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 22 Dec 2011 13:10:02 +0200 Subject: [PATCH] ASoC: omap-abe-twl6040: DAI link selection based on platform data We can have machines without DMIC connected. In this case there is no need to create amother (unusable) capture PCM on the card. The existence of the DMIC connection can be checked via pdata->has_dmic. Select the correct dai_link structure for the card based on pdata->has_dmic.
