ipack_device_init(9)

💖 ipack_device_init(9) 💖

okay so this is a page from the Kernel API Manual, and it's about ipack_device_init — the function that gets your brand-new IPack device all glowed up and ready for the world ✨

---

🌸 NAME 🌸

ipack_device_init — initialize an IPack device. that's it, that's the whole vibe 🫶

---

✨ SYNOPSIS ✨

int ipack_device_init (struct ipack_device *dev );

---

🎀 ARGUMENTS 🎀

• dev — the new device you're about to initialize. the main character of this whole operation 💅

---

🦋 DESCRIPTION 🦋

So bestie, here's what's going on: this function initializes a brand-new IPack device (and yes, in IndustryPack jargon it's called a "module" — iykyk, they love confusing names fr fr).

The call is made by the carrier driver, okay? That's who's responsible here.

Now listen up, because this part matters 🙈 — before the carrier calls this function, it should already have populated these fields on dev:

• bus
• slot
• the region array

That's the carrier's job, not yours, not this function's. The rest of the fields will get allocated and populated during initialization — this function handles all that for you, slay 💖

---

⭐ RETURN ⭐

• zero on success 🎉
• an error code on failure 😭

(the classic zero-or-error situation, no surprises)

---

🔥 NOTE 🔥

_Never_ directly free dev after calling this function. Even if it returned an error. Like, especially not then, okay? 🫠

Always use ipack_put_device to give up the reference that was initialized in this function instead. That's the only correct move, periodt 💅
