[alsa-devel] [PATCH 4/5] ASoC: RX-51: Convert to table based DAPM setup

[Sebastian Reichel]

Use table based setup to register the DAPM widgets and routes. This on one hand
makes the code a bit 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. This fixes an issue with double prefixing of routes.
