[alsa-devel] [PATCH 2/4][RESEND] ASoC: remove unneeded dai->driver check

[Kuninori Morimoto]

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

On soc_add_dai(), it is checking dai->driver->xxx,
This means, dai->driver is mandatory, never been NULL.
dai->driver check is not needed.
This patch removes it.
