devm_pinctrl...ter_and_init(9)

💅 devm_pinctrl...ter_and_init(9) — like, the Kernel API Manual, bestie 🎀

okay so real talk: this is a page straight out of the Kernel API Manual, and it's about devm_pinctrl_register_and_init. yes the title is lowkey chopped in half (devm_pinctrl...ter_and_init(9)) — that's just how the manpage do. anyway. sit down, hydrate, let's go ✨

🌸 NAME 🌸

devm_pinctrl_register_and_init — the resource-managed version of "register and init" for pinctrl. she registers AND inits, and she cleans up after herself. main character energy fr fr 💅

---

✨ SYNOPSIS ✨

int devm_pinctrl_register_and_init (struct device *dev , const struct
pinctrl_desc *pctldesc , void *driver_data , struct pinctrl_dev
**pctldev );

like, look at her. four arguments, returns an int. slay 🫶

---

🦋 ARGUMENTS 🦋

• dev — the parent device for this pin controller. the momager, basically 👑
• pctldesc — the descriptor for this pin controller. the whole blueprint vibe check 🌈
• driver_data — private pin controller data for this pin controller. her personal little diary, nobody else's business 🙈
• pctldev — the pin controller device. this is where the controller device pointer lands, bestie 📍

---

💖 DESCRIPTION 💖

Returns zero on success or an error number on failure. that's it, that's the contract. zero = we ate 🔥, error number = we did NOT eat 😭

The pinctrl device will be automatically released when the device is unbound. that's the whole devm_ thing — she's resource managed, so the cleanup is literally automatic. no manual put-ing, no leaked vibes, no 3am debugging session. iconic behavior, genuinely 🧚
