snd_ctl_free_one(9)

🌸 NAME 🌸

okay bestie, this is snd_ctl_free_one — release the control instance — straight from the Kernel API Manual. She has one job and she absolutely ate. 💅✨

✨ SYNOPSIS ✨

void snd_ctl_free_one (struct snd_kcontrol *kcontrol );

🎀 ARGUMENTS 🎀

• kcontrol — the control instance, aka the lil guy you're freeing 🫶

💅 DESCRIPTION 💅

okay so real talk: this releases the control instance created via snd_ctl_new or snd_ctl_new1. That's the whole vibe. ✨

🚨 bestie, do NOT call this after the control has been added to the card. Like, no cap, don't. That is not the move. 🙈💀
