From a73fb2df01866b772a48fab93401fe3edbe0b38d Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 7 Mar 2012 10:38:26 +0000 Subject: ASoC: dapm: Use DAPM mutex for DAPM ops instead of codec mutex It has now become necessary to use a DAPM mutex instead of the codec mutex to lock the DAPM operations. This is due to the recent multi component support and forth coming Dynamic PCM updates. Currently we lock DAPM operations with the codec mutex of the calling RTD context. However, DAPM operations can span the whole card context and all components. This patch updates the DAPM operations that use the codec mutex to now use the DAPM mutex PCM subclass for all DAPM ops. We also add a mutex subclass for DAPM init and PCM operations.
