From e37a4970cd7ab6aec9e848cd3c355fd47fd18afd Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Wed, 2 Mar 2011 18:21:57 +0000 Subject: [PATCH] ASoC: Add a per-card DAPM context This means that rather than adding the board specific DAPM widgets to a random CODEC DAPM context they can be added to the card itself which is a bit cleaner. Previously there only was one DAPM context and it was tied to the single supported CODEC.
