qc_usb_audio...load_suspend(9)

💅 qc_usb_audio_offload_suspend — from the Kernel API Manual, section 9, bestie

okay so picture this: it's a whole kernel API manual page, and the star of the show is qc_usb_audio_offload_suspend. yes the header line literally says qc_usb_audio...load_suspend(9) because they truncate the vibe, and yes it's the same function, we're not doing anything weird here 🫶

✨ NAME ✨

qc_usb_audio_offload_suspend — the USB offload PM suspend handler. that's it. that's the whole name. it suspends, it's PM, it's offload. iconic behavior honestly 👑

---

🎀 SYNOPSIS 🎀

void qc_usb_audio_offload_suspend (struct usb_interface *intf ,
pm_message_t message );

returns void — so like, don't go looking for a return value, she gives you nothing back and she's at peace with that ✨

🦋 ARGUMENTS 🦋

• intf — the USB interface. the actual device-side bestie this handler is dealing with 💖
• message — the suspend type. like, which flavor of suspend are we talking about. it matters 🍓

---

💀 DESCRIPTION 💀

so this is a PM suspend handler. its whole job? make sure the USB offloading driver stops any pending traffic, so that the bus can actually be suspended. that's the assignment, and it ate 🔥

no cap — if pending traffic is still chilling there, the bus can't suspend, so this handler is basically the friend who makes everyone wrap it up so y'all can leave the party 🌸
