💖 NAME 💖

ok so bestie, this is snd_soc_runtime_calc_hw — it literally calculates the hw limits for a PCM stream ✨ that's the whole vibe, no cap.

🌸 SYNOPSIS 🌸

int snd_soc_runtime_calc_hw (struct snd_soc_pcm_runtime *rtd , struct
       snd_pcm_hardware *hw , int stream );

🎀 ARGUMENTS 🎀

• rtd — the ASoC PCM runtime, the main character of this whole saga 👑
• hw — the PCM hardware parameters. heads up bestie, this one is an output — it's giving "results go here" 💅
• stream — which direction the PCM stream is going 🦋

✨ DESCRIPTION ✨

okay so what this does: it calculates the subset of stream parameters that are supported by all the DAIs associated with the PCM stream. every single one of them has to agree — it's a group project and they all gotta sign off fr fr 🫶
