gpiod_to_irq(9)

✨ gpiod_to_irq(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 this one's a lil function from the kernel's GPIO corner of the world, and honestly it's giving "short but powerful."

---

🌸 NAME 🌸

gpiod_to_irq — return the IRQ corresponding to a GPIO 🎀

---

⭐ SYNOPSIS ⭐

int gpiod_to_irq (const struct gpio_desc *desc );

---

🦋 ARGUMENTS 🦋

• desc — the gpio whose IRQ will be returned (already requested). like, it has to be already requested, no cap — that's part of the deal ✨

---

🔥 RETURN 🔥

The IRQ corresponding to the passed GPIO, or an error code in case of error. that's it, that's the whole vibe — you get your IRQ, or you get an error code, no in-between 💀
