💅 usb_gadget_r...driver_owner(9) 💅

okay so this is from the Kernel API Manual, and the full name of the page is usb_gadget_r...driver_owner(9) — yes it's truncated with the ... and no, that's not me being lazy, that's literally how it's printed, iykyk. anyway bestie, this one is about registering a gadget driver and it's honestly kind of a big deal 🎀

---

✨ NAME ✨

usb_gadget_register_driver_owner — register a gadget driver. that's it, that's the whole name section, short and iconic 💖

---

🦋 SYNOPSIS 🦋

int usb_gadget_register_driver_owner (struct usb_gadget_driver *driver ,
struct module *owner , const char *mod_name );

like, copy it exactly bestie, don't get creative with the spacing 💀

---

🌸 ARGUMENTS 🌸

• driver — the driver being registered. the main character, fr 👑
• owner — the driver module. the module that owns it 🫶
• mod_name — the driver module's build name. yes it's a different thing from owner, don't @ me 🙈

---

⭐ CONTEXT ⭐

can sleep 😴 — so like, you're allowed to block here, no panic needed, we're chilling

---

🔥 DESCRIPTION 🔥

okay so here's the vibe: you call this in your gadget driver's module initialization function, and its whole job is to tell the underlying UDC controller driver about your driver. communication! 💬✨

the bind function will be called to bind it to a gadget before this registration call returns — so it happens inside the call, not later, not via some callback down the line, before it returns, periodt ⏱️

and it's expected that the bind function will be in init sections. just how it's supposed to be, no cap 💅

⚠️ also, big one: use the macro defined below instead of calling this directly. like, do not raw-dog this function call bestie, the macro is right there, it's giving "the API wants you to use the wrapper" 😭
