[alsa-devel] [PATCH] ASoC: migor: Convert to table based DAPM setup

Mon Mar 3 08:14:14 CET 2014


Use table based setup to register the DAPM widgets and routes.  This on one hand
makes the code a bit shorter and cleaner and on the other hand the board level
DAPM elements get registered in the card's DAPM context rather than in the
CODEC's DAPM context.
