💖 devm_regmap_init_fsi (9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for devm_regmap_init_fsi, and it's honestly lowkey iconic. we're setting up a register map, but the managed way, which means you don't have to clean up after yourself. main character energy fr fr 🎀

✨ NAME ✨

devm_regmap_init_fsi — Initialise managed register map 🦋

---

🌸 SYNOPSIS 🌸

devm_regmap_init_fsi (fsi_dev , config );

---

💅 ARGUMENTS 💅

• fsi_dev — the Device that will be interacted with 🫶 like, this is the thing you're talking to, periodt.
• config — Configuration for register map ⭐ — all the setup deets go in here.

---

🔥 DESCRIPTION 🔥

so here's the vibe check 👑: the return value will be an ERR_PTR on error, or a valid pointer to a struct regmap. that's it, that's the deal.

and the best part? the regmap will be automatically freed by the device management code 😭💖 no manual cleanup, no "did i remember to free it", none of that — it's giving handled. obsessed.

ngl bestie, do check that return value — ERR_PTR means something went wrong, and you'll want to know about it 🙈
