devm_regmap_init_i3c(9)

💅 devm_regmap_init_i3c(9) ✨

okay bestie, welcome to the Kernel API Manual — this is the one that spins up a managed register map for an I3C device, and honestly? it's giving "the kernel will clean up after you" main character energy 🫶

---

🌸 NAME 🌸

devm_regmap_init_i3c — init a register map, but make it managed 💖

---

✨ SYNOPSIS ✨

devm_regmap_init_i3c (i3c , config );

---

🎀 ARGUMENTS 🎀

• i3c — the device you're gonna be interacting with, no cap 🦋
• config — the configuration for the register map, aka how you want this thing set up ⭐

---

💜 DESCRIPTION 💜

So here's the tea ☕: what you get back is either an ERR_PTR if something went wrong 😭, or a valid pointer to a struct regmap if it slayed 🔥.

And the iconic part? The regmap gets automatically freed by the device management code. Not you. Never you. Device management handles it, periodt 💅✨

lowkey obsessed with how this whole list is just the regmap init extended universe 🌌 iykyk

and that's the whole page, bestie 💖 straight from ./include/linux, dated October 2026, and yeah — the footer still says devm_regmap_init_i3c(9) because some things never change 😌 mwah 💋
