From 848dd8beef44df18f2eb61e00981b0692adb801b Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 27 Apr 2011 18:16:32 +0100 Subject: ASoC: Add more natural support for no-DMA DAIs Since we can now support multiple platforms allow machines to not specify a platform in a DAI link. Since the rest of the code requires that we have a struct device for all objects we do this by substituting in a dummy device that we register automatically.
