i3c_dev_get_master_data(9)

💅 i3c_dev_get_master_data 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this one's a tiny little function living in i3c_dev_get_master_data(9) land, and honestly? it's giving "small but mighty" 🎀

---

🌸 NAME 🌸

i3c_dev_get_master_data — get master private data attached to an I3C device descriptor 🦋

like, it goes and fetches the private data that some master parked on an I3C device descriptor. that's the whole vibe check, no cap.

---

✨ SYNOPSIS ✨

void * i3c_dev_get_master_data (const struct i3c_dev_desc *dev );

literally one argument. one return. immaculate minimalism 👑

---

🫶 ARGUMENTS 🫶

• dev — the I3C device descriptor you wanna pull private data out of. that's it, that's the whole parameter. it's const struct i3c_dev_desc * so like, don't even think about messing with it 🙈

---

💖 RETURN 💖

returns the private data that was previously attached with i3c_dev_set_master_data — y'know, the matching setter, the other half of the duo 💅

or, if nobody attached anything to the device: NULL. that's it. no data attached, no data back, zero drama, fr fr.
