[PATCH] ASoC: simple-card-utils: Avoid over-allocating DLCs

[Kuninori Morimoto]

Hi Samuel

Thank you for your patch

> The allocation of the DAI link components (DLCs) passed the wrong
> pointer to sizeof. Since simple_dai_props is much larger than
> snd_soc_dai_link_component, there was no out of bounds access, only
> wasted memory.
