💅 regmap_init_spmi_ext(9) — the Kernel API Manual, bestie edition 🎀

okay so this one lives in the Kernel API Manual, and it's literally the glow-up moment where you get a regmap for the Ext register space. yes. that Ext. slay.

✨ NAME ✨

regmap_init_spmi_ext — create a regmap for the Ext register space 🦋

---

🌸 SYNOPSIS 🌸

regmap_init_spmi_ext (dev , config );

---

💖 ARGUMENTS 💖

• dev — the device you're gonna be interacting with 🫶
• config — the configuration for the register map, iykyk

---

👑 DESCRIPTION 👑

so the return value is gonna be one of two things, and the vibe check matters here:

• an ERR_PTR if something went wrong 😭
• or a valid pointer to a struct regmap ✨ (this is the one we want, fr fr)

that's it. that's the whole description. short and iconic, periodt.
