✨ gpio_led_register_device(9) ✨

okay bestie, welcome to the Kernel API Manual page for gpio_led_register_device(9) — manual name folded in right here, cute and accounted for 💅. This one is all about registering a gpio-led device, and it’s lowkey iconic.

---

🌸 NAME 🌸

gpio_led_register_device — register a gpio-led device 🎀

---

✨ SYNOPSIS ✨

struct platform_device * gpio_led_register_device (int id , const struct
       gpio_led_platform_data *pdata );

---

🎀 ARGUMENTS 🎀

• id — the platform ID. That’s the whole vibe check for this one 🫶
• pdata — the platform data used for the new device. It’s giving “blueprint for the new leds-gpio device” ✨

---

💖 DESCRIPTION 💖

okay so here’s the tea ☕: this function makes a copy of pdata and pdata->leds, and registers a new leds-gpio device with the result. The way that works is honestly kind of a slay 💅.

It lets pdata and pdata-leds live in .init.rodata, and that saves some bytes compared to a static struct platform_device with static platform data. no cap, that’s the glow-up 🌈.

It returns the registered device or an error pointer. Those are the options, bestie 💖.
