[1/8] ASoC: rename rtd->num to rtd->id

Commit Message

Kuninori Morimoto Oct. 24, 2024, 1:29 a.m. UTC

Current rtd has "num". It sounds/looks like size of rtd or something,
but it will be mainly used at snd_pcm_new() as "device index".
This naming is confusable. Let's rename it to "id"

Some drivers are using rtd->num, so let's keep it so far, and remove
it if all user was switched.
