💖 qc_usb_audio_offload_init_qmi_dev(9) 💖

okay so bestie, welcome to the Kernel API Manual — this is section 9 of the manual, and today's main character is qc_usb_audio_offload_init_qmi_dev. she's a lil' initialization function and she ate, honestly 🎀

---

✨ NAME ✨

qc_usb_audio_offload_init_qmi_dev — literally just initializes the qmi dev. that's her whole job. no cap 💅

---

🌸 SYNOPSIS 🌸

int qc_usb_audio_offload_init_qmi_dev (void );

---

🦋 ARGUMENTS 🦋

• void — no arguments, bestie. she takes zero notes, zero parameters, nothing. you walk in, you call her, that's it 🙈

---

👑 DESCRIPTION 👑

So here's the vibe: this function initializes the USB qdev, and that device is the one carrying all the info pertaining to the offloading resources. it's giving messenger energy, honestly ✨

And here's the important bit — the way this device works, it only gets freed when there are no longer any offloading candidates left. like, translation? when all the audio devices are disconnected. so she does NOT pack her bags early. she stays until literally everyone's gone 😭💀
