[alsa-devel] [PATCH 2/2] ASoC: neo1973_wm8753: Convert to table based setup

[Lars-Peter Clausen]

Use table based setup to register the controls and 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.
