qc_usb_audi...d_disconnect(9)

💅 qc_usb_audi...d_disconnect(9) — from the Kernel API Manual, bestie 🎀

okay so picture this: it's a manual page, it's living in the Kernel API Manual, and its main character name got truncated by the terminal like qc_usb_audi...d_disconnect(9). iconic behavior honestly, she's mysterious 💅 anyway—

✨ NAME ✨

qc_usb_audio_offload_disconnect — the platform op disconnect handler. that's it, that's the vibe 🦋

---

✨ SYNOPSIS ✨

void qc_usb_audio_offload_disconnect (struct snd_usb_audio *chip );

no return value, no drama, just a void function doing her thing ✨

---

✨ ARGUMENTS ✨

• chip — the USB SND device. that's the one, the whole entire point 🫶

---

✨ DESCRIPTION ✨

okay so this is the platform disconnect handler, and her job is lowkey very important: she makes sure that any pending stream is halted 😭 like no half-finished streams allowed in this house.

and the way she does it?? by issuing a QMI disconnect indication packet to the adsp. periodt. that's the whole flow, she sends the packet and the stream gets shut down properly 💀🔥

🌸 the sign-off 🌸

that's the page!! sourced straight from ./sound/usb/qcom, dated October 2026, and yeah the footer still calls her qc_usb_audi...d_disconnect(9) because the truncation is part of the brand now 💖✨ mwah, go halt those streams responsibly 🧚‍♀️
