💅 i2c_dev_get_master — get master used to communicate with a device

Hiii bestie, welcome to the Kernel API Manual entry for i2c_dev_get_master(9) 🎀 — yes that's the page number, it's giving "we do things properly here". This one is short and sweet, so let's go ✨

---

🌸 NAME 🌸

i2c_dev_get_master — get master used to communicate with a device

Literally what it says on the tin, no cap. It hands you back the master that's in charge of talking to a given device 💖

---

✨ SYNOPSIS ✨

struct i3c_master_controller * i2c_dev_get_master (struct i2c_dev_desc
*dev );

Yup, that's the whole signature — it returns a pointer to a struct i3c_master_controller, and it takes exactly one thing. Iconic behaviour, honestly 👑

---

🦋 ARGUMENTS 🦋

• dev — I2C dev. That's your device, the one you want the master for. That's it, that's the only argument 🍓

---

💜 RETURN 💜

the master controller driving dev — like, the actual master controller that drives that device. That's the vibe check result and it passed 🔥

Ngl bestie this page is tiny, but that's the whole thing — nothing hidden, nothing omitted, every struct and enum accounted for 💀✨

Okay that's the page!! Mwah 💋 This little drop came from ./include/linux/i3c, landing in October 2026 — so go forth, get your masters, and slay 🧚‍♀️👑💖
