ASoC: soc-core: add asoc_rtd_to_cpu/codec() macro
Now, snd_soc_pcm_runtime supports multi cpu_dai/codec_dai.
It still has cpu_dai/codec_dai for single DAI,
and has cpu_dais/codec_dais for multi DAIs.
dais = [][][][][][][][][][][][][][][][][][]
^cpu_dais ^codec_dais
|--- num_cpus ---|--- num_codecs --|
/* for multi DAIs */
rtd->cpu_dais = &rtd->dais[0];
rtd->codec_dais = &rtd->dais[dai_link->num_cpus];
/* for single DAI */
rtd->cpu_dai = rtd->cpu_dais[0];
rtd->codec_dai = rtd->codec_dais[0];
But, these can be replaced by dais.
This patch adds asoc_rtd_to_cpu() / asoc_rtd_to_codec() macro for it.
