devm_regmap_init_spi(9)

devm_regmap_init_spi(9) ✨💅

okay so this page is from the Kernel API Manual, and it's literally about initialising a register map for SPI devices, bestie. no cap, it's giving “kernel dev but make it cute” energy 🎀

---

🌸 NAME 🌸

devm_regmap_init_spi — Initialise register map

---

✨ SYNOPSIS ✨

devm_regmap_init_spi (dev , config );

---

🫶 ARGUMENTS 🫶

• dev — Device that will be interacted with
• config — Configuration for register map

---

💖 DESCRIPTION 💖

so like, the return value? it's gonna be an ERR_PTR if things go wrong 😭 or a valid pointer to a struct regmap if we're slaying ✨ and the map? it gets automatically freed by the device management code, periodt. no manual cleanup arc needed, iykyk 💅

and that's the page, bestie 💖 it lives in ./include/linux, dated October 2026, and it's literally devm_regmap_init_spi(9) — periodt 🦋✨
