[alsa-devel] [PATCH 1/5] ASoC: Remove card's DAI list

[Lars-Peter Clausen]

Commit f0fba2ad1 ("ASoC: multi-component - ASoC Multi-Component Support") added
a per card list that keeps track of all the DAIs that have been registered with
the card, but the list has never been used. This patch removes it again.
