✨ cdns3_req_e...onfiguration(9) ✨

okay so bestie, we're in the Kernel API Manual today 💅 and this little cutie is a kernel function page — like, actual Linux kernel docs, the final boss of documentation. don't panic, it's short and honestly kind of iconic. let's get into it 🎀

---

🌸 NAME 🌸

cdns3_req_ep0_set_configuration — the girlies who handle the SET_CONFIG standard USB request 🦋 lowkey the whole job description right there.

---

✨ SYNOPSIS ✨

int cdns3_req_ep0_set_configuration (struct cdns3_device *priv_dev ,
       struct usb_ctrlrequest *ctrl_req );

that's the whole signature, no cap. returns an int, takes two pointers, we move 🌈

---

💖 ARGUMENTS 💖

• priv_dev — the extended gadget object. yes bestie, extended, it's giving main character energy 👑
• ctrl_req — a pointer to the received setup packet. it's literally the packet that showed up at the door 🙈

---

🔥 DESCRIPTION 🔥

here's the vibe check on what it gives back 👇

• returns 0 if success — slay, we ate 💅
• returns USB_GADGET_DELAYED_STATUS when the status stage is deferred — not a flop, it's just postponed, iykyk ⭐
• returns an error code on error — yeah, that one's gonna sting 😭

fr fr that's the entire description. no extra lore, no secret behaviour, don't let anyone tell you otherwise.
