✨ uaudio_event...cleanup_free(9) ✨

okay so bestie, welcome to the Kernel API Manual 💖 this one's a lil page about uaudio_event_ring_cleanup_free — the function, not the whole manpage name, don't come for me 🎀

---

🌸 NAME 🌸

uaudio_event_ring_cleanup_free — cleanup secondary event ring 🧹✨

---

🦋 SYNOPSIS 🦋

void uaudio_event_ring_cleanup_free (struct uaudio_dev *dev );

like, that's the whole signature. void, no return value, no notes. main character energy tbh 👑

---

💅 ARGUMENTS 💅

• dev — usb offload device 🫶 that's the one and only thing you hand it.

---

👑 DESCRIPTION 👑

Cleans up the secondary event ring that was requested. 💀 yes it's really just that.

This will occur when the adsp is no longer transferring data on the USB bus across all endpoints. so like, all endpoints are done, adsp has left the group chat, and that's when the cleanup happens. no cap 🧚
