💅 dev_to_i3cdev

okay so bestie, welcome to the Kernel API Manual page for dev_to_i3cdev — yes it's a kernel function, yes it's short, and yes it's still iconic. this is the one that hands you back the I3C device that's wrapped around a struct device. lowkey a container_of situation but make it fashion ✨

dev_to_i3cdev — returns the I3C device containing @dev

like, you give it a device, it gives you the I3C device it lives inside. that's the whole vibe. no cap 🫶

---

🎀 SYNOPSIS 🎀

dev_to_i3cdev (__dev );

that's it. that's the call. she's simple, she's neat, she slays 💅

---

🦋 ARGUMENTS 🦋

• __dev — device object. literally just hand her the device and she'll do the rest 🍓

---

⭐ RETURN ⭐

a pointer to an I3C device object. that's the whole payoff, bestie — you put in a device, you get back the I3C device, main character energy all around 👑
