ipack_bus_register(9)

✨ NAME ✨

ipack_bus_register — bestie, this is the one that registers a brand-new ipack bus 🎀 (this page lives in the Kernel API Manual, section 9, iykyk)

---

🌸 SYNOPSIS 🌸

struct ipack_bus_device * ipack_bus_register (struct device *parent ,
       int slots , const struct ipack_bus_ops *ops , struct module *owner );

---

🦋 ARGUMENTS 🦋

• parent — a pointer to the parent device, if there is one at all (no pressure, it's optional energy ✨).
• slots — how many slots the bus device has available, like literally the slot count 💅.
• ops — the bus operations for the mezzanine drivers. yes, the whole ops vibe, hand it over 🫶.
• owner — ok so the original page literally just says -- undescribed -- and honestly? not me exposing the manpage like this 💀 we move on.

---

💖 DESCRIPTION 💖

So here's the tea: the carrier board device should call this function to register itself as an available bus device in ipack. that's the whole assignment. main character energy, but make it a bus device 👑

ngl it's giving "hi yes I exist, I'm a bus now, come find me in ipack."

---

🌈 RETURN 🌈

• NULL on error 😭
• struct ipack_bus_device on success 🎉 slay
