[alsa-devel] [PATCH 12/19] ASoC: rsnd: use function pointer for each probe

[Kuninori Morimoto]

From: Kuninori Morimoto <kuninori.morimoto.gx at renesas.com>

R-Car sound consists of many devices.
It will have more device support in the future.
Thus, for each probe become now function pointer array.
