💅 NAME 💅

ipc4_probes_deinit — cleanup after data probing

okay bestie, this page is from the Kernel API Manual, and it's literally the cleanup era for data probing. no cap. 🫶

---

✨ SYNOPSIS ✨

int ipc4_probes_deinit (struct sof_client_dev *cdev );

---

🎀 ARGUMENTS 🎀

• cdev — SOF client device. that's the one and only argument, bestie 💖

---

🌈 RETURN 🌈

• 0 on success
• negative error code on error

so iconic when it's 0, and when it's negative? that's the error code saying nope 💀

---

🦋 DESCRIPTION 🦋

okay so here's the vibe: the Host sends a DEINIT request to free a previously initialized probe on the DSP side once it is no longer needed. literally cleanup time, periodt. ✨

and the important caveat, fr fr: DEINIT only when there are no probes connected and with all injectors detached. that's the condition, bestie — not a suggestion. 😭
