ASoC: Add card driver data (dddf3e4c) · Commits · 戴 / test

Provide driver data for cards within the card structure. To simplify the implementation of the PM operations we don't use the struct device driver data as this is used by the core to retrieve the card in callbacks from the device model and PM core. Signed-off-by:
