The DAI link array and the properties (fmt, sysclk slots) are hard-coded for a single CPU / CODEC link.
This patch dynamically allocates the DAI link array and the properties with the aim of supporting many DAI links.

This is only an implementation detail, but wouldn't it produce a cleaner implementation if you would write the above structure like this:
struct simple_card_data { struct snd_soc_card snd_card; struct simple_dai_links { struct snd_soc_dai_link dai_link; struct asoc_simple_dai cpu_dai; struct asoc_simple_dai codec_dai; } *dai_links; };
or even
struct simple_card_data { struct snd_soc_card snd_card; struct simple_dai_links { struct snd_soc_dai_link dai_link; struct asoc_simple_dai cpu_dai; struct asoc_simple_dai codec_dai; } dai_links[]; /* dynamically allocated */ };
But, as said this only an implementation detail.
