💅 sdca_asoc_free_constraints(9)

okay so this is a page straight out of the Kernel API Manual, and bestie, it's a short one but it matters. Let's get into it ✨

🌸 NAME

sdca_asoc_free_constraints — literally just frees the constraint allocations 🧹💖

🦋 SYNOPSIS

void sdca_asoc_free_constraints (struct snd_pcm_substream *substream ,
struct snd_soc_dai *dai );

no return value, no drama, it just does the thing 🫶

🎀 ARGUMENTS

• substream — a pointer to the PCM substream 👑 (yes, the actual struct snd_pcm_substream *, keep it exactly like that)
• dai — a pointer to the ASoC DAI 🌈

💜 DESCRIPTION

Typically called from shutdown. that's it. that's the whole vibe check 💀 but like — it's the cleanup era, bestie, someone's gotta release those constraint allocations and it's her 🌟
