From 67850a892bf627e1c627bc8d0bcd84b90ecc9d7f Mon Sep 17 00:00:00 2001 From: Dimitris Papastamos Date: Tue, 22 Mar 2011 10:36:57 +0000 Subject: [PATCH] ASoC: Add control_type in snd_soc_codec This is mainly used by the soc-cache code to easily determine the currently used underlying serial bus. Set SND_SOC_CUSTOM to 1 so we can distinguish it if it is not initialized or set.
