💖 adis_init(9) — it's giving "Kernel API Manual" ✨

okay so bestie, welcome to adis_init(9) from the Kernel API Manual, and like… this is the first thing you call. Like the main character of initialization. periodt.

🌸 NAME 🌸

adis_init — initialize the adis device structure 💅 (yes that's the whole name section, she's short and iconic)

---

✨ SYNOPSIS ✨

int adis_init (struct adis *adis , struct iio_dev *indio_dev , struct
spi_device *spi , const struct adis_data *data );

like yes, it returns an int, and yes there are four args, don't panic 🫶

---

🎀 ARGUMENTS 🎀

• adis — the adis device 🦋
• indio_dev — the iio device ⭐
• spi — the spi device 🌈
• data — chip specific data 👑

---

🦋 DESCRIPTION 🦋

so here's the tea: it returns 0 on success, and a negative error code otherwise 💖 like if you get a negative back, that's your sign, no cap.

🚨 the big one: this function must be called before any other adis helper function may be called. like literally, respect the order. she's the opener, the others are the set. don't skip her, i'm begging 😭
