devm_iio_map_array_register(9)

💖 devm_iio_map_array_register — kernel API manual, but make it cute 💖

okay so bestie, welcome to the devm_iio_map_array_register(9) page — yes that's the whole name, it's a mouthful, we don't talk about it 😭. It's a kernel API manual entry, and it's literally the device-managed glow-up of iio_map_array_register. main character energy only ✨

---

✨ NAME ✨

devm_iio_map_array_register — the device-managed version of iio_map_array_register. that's it, that's the vibe 💅

---

🦋 SYNOPSIS 🦋

int devm_iio_map_array_register (struct device *dev , struct iio_dev
       *indio_dev , const struct iio_map *maps );

like, three args, one int coming back at you, no cap 🫶

---

🌸 ARGUMENTS 🌸

• dev — the device object you're binding the unwinding of this registration to. it's the one holding the leash, basically 🧚
• indio_dev — pointer to the iio_dev structure. iconic struct, we love her 👑
• maps — pointer to an IIO map object that's getting registered to this IIO device. the actual payload, fr fr 🎀

---

🔥 DESCRIPTION 🔥

so here's the tea 🍓 — this function will call iio_map_array_register to register an IIO map object, and it also hooks a callback to the iio_map_array_unregister function to handle the de-registration of the IIO map object when the device's refcount goes to zero. automatic cleanup, no manual labour, obsessed 😭✨

like, you register the thing, and devm handles the messy breakup later when the refcount hits zero. it's giving responsible adult behaviour 💜

ngl bestie, the SEE ALSO section is literally the friend group. the register, the unregister, and the header they all live in. periodt 💅
